FAQ
- There are other factors that cause motor vibration and noise!
Axial vibration and noise of end caps
The axial vibration of the end cover is 1 of the sources of mechanical noise, which is mainly excited by the bearing vibration, which is more important in small motors. The smaller the axial dynamic stiffness of the end cover, the easier it is to excite larger vibration speed and noise.
Vibration and noise of the brush unitThe vibration and noise of the brush device are caused by the poor surface condition of the commutator, the large gap between the brush and the brush holder, the small brush pressure or the improper pressure application which makes the brush skew, and the brush holder, brush holder and brush rod. It is caused by structural and technological reasons such as insufficient stiffness.
When the DC motor is running, the sliding contact condition of the brush and the commutator, as well as the cuprous oxide film formed on the surface of the commutator and a layer of graphite film and dust particles covered on it, not only affect the commutation performance of the motor, but also affect the commutation performance of the motor. to vibration and noise.
Practice has proved that due to the low temperature of the sliding contact surface at no load, the above-mentioned film is not easy to form, and the dry friction between the brush and the commutator increases the noise. For example, when the no-load operation cycle of the rolling DC motor accounts for more than 50% of the total time, the noise under no-load conditions is 6~10dB higher than that under load. This vibration is different from the vibration of the commutator surface due to mechanical reasons, which can be detected when the motor is running at low speed (vibration is felt when the brush is touched by hand). The frequency spectrum of brush vibration noise generated by sliding contact is generally in the range of 1000~-8000Hz, and it does not change much when the motor speed changes, which is 1 of the characteristics that distinguish it from mechanical reasons.
The brush vibration noise produced by the sliding contact is also related to the brush polarity. For example, the positive brush of a DC generator has less vibration than the negative brush; because the positive brush can separate graphite and carbon crystals, absorb moisture on the surface of the commutator to form a lubricating film, and the negative brush removes it. The formation of the sliding contact film is also related to the grade of the brush. The selection of the grade is first to ensure good commutation performance, but at the same time, the vibration and noise of the brush should also be considered.
In addition to mechanical noise, aerodynamic noise is also a major problem in motor noise control. Especially for high-speed motors, this problem is relatively concentrated. In the tweet after bearing, Ms. participated in the meeting and chose some content to share with you.

What are the main components of a DC motor, and how do they contribute to its functionality?
A DC (Direct Current) motor consists of several key components that work together to enable its functionality. Each component plays a crucial role in the operation of the motor. Here’s a detailed explanation of the main components of a DC motor and their contributions:
1. Stator:
The stator is the stationary part of the motor. It typically consists of permanent magnets or electromagnets that produce a fixed magnetic field. The stator’s magnetic field interacts with the rotor’s magnetic field to generate the required torque for motor rotation. The stator provides the foundation for the motor’s magnetic field and contributes to its overall stability and efficiency.
2. Rotor:
The rotor is the rotating part of the motor and is connected to the motor’s output shaft. It contains coils or windings that carry the armature current. The rotor’s windings interact with the stator’s magnetic field, resulting in the generation of a mechanical force that causes the rotor to rotate. The rotor’s movement is responsible for converting electrical energy into mechanical motion, enabling the motor to perform its intended function.
3. Armature:
The armature is the core of the rotor that holds the armature windings. The armature windings are typically made of copper wire and are evenly spaced around the armature. When a current passes through the armature windings, a magnetic field is created around them. This magnetic field interacts with the stator’s magnetic field, resulting in the generation of a torque that drives the rotor’s rotation. The armature is a critical component that facilitates the conversion of electrical energy into mechanical energy.
4. Commutator:
The commutator is a cylindrical ring attached to the rotor shaft. It consists of multiple segments, usually made of copper, that are insulated from each other. The commutator plays a vital role in the DC motor’s operation by providing the necessary electrical connections to the armature windings. As the rotor spins, the brushes make physical contact with different commutator segments, effectively reversing the direction of the current in the armature windings at the appropriate timing. This reversal of current flow ensures that the torque generated in the armature windings is always in the same direction, allowing for continuous rotation of the rotor.
5. Brushes:
The brushes are stationary contacts that make physical contact with the commutator segments. They are typically made of carbon or graphite and provide electrical connections to the armature windings. The brushes supply the current to the armature windings through the commutator, allowing for the creation of the magnetic field necessary for motor operation. The brushes need to maintain proper contact with the commutator to ensure efficient electrical transmission and reliable motor performance.
6. Housing or Frame:
The housing or frame of the DC motor encloses and supports all the internal components. It provides structural integrity, protects the motor from external elements, and helps dissipate heat generated during operation. The housing or frame also serves as a mounting point for the motor, allowing it to be securely installed in various applications.
By understanding the main components of a DC motor and their contributions, one can gain insights into how each part works together harmoniously to achieve the desired motor functionality.
Can you explain the concept of armature winding in a DC motor?
In a DC (Direct Current) motor, the armature winding is a crucial component that plays a significant role in the motor’s operation. It is responsible for producing the magnetic field that interacts with the stator’s magnetic field, resulting in the generation of torque and the rotation of the motor. Here’s a detailed explanation of the concept of armature winding in a DC motor:
The armature winding is a coil or set of coils made of insulated wire that is wound around the armature core, which is typically a laminated iron core. The armature winding is located on the rotor of the motor and is connected to the commutator. It carries the armature current, which is the current that flows through the winding to create the magnetic field. The armature winding is usually made of copper wire due to its excellent electrical conductivity.
When a current passes through the armature winding, it generates a magnetic field around the winding according to Ampere’s circuital law. The direction of the magnetic field is determined by the right-hand rule, where the thumb represents the direction of the current flow, and the curled fingers indicate the direction of the magnetic field.
The interaction between the magnetic field produced by the armature winding and the magnetic field produced by the stator’s permanent magnets or electromagnets creates a mechanical force, known as torque. This torque causes the rotor to rotate, converting electrical energy into mechanical motion.
The armature winding is designed in such a way that it produces a multipole magnetic field. The number of poles in the winding corresponds to the number of poles in the stator’s magnetic field. This ensures that the magnetic fields of the armature and stator are properly aligned for efficient torque generation.
The armature winding is connected to the commutator, which is a cylindrical ring with multiple segments that are insulated from each other. As the rotor spins, the brushes make physical contact with different segments of the commutator, effectively reversing the direction of the current in the armature winding. This reversal of current flow ensures that the torque generated in the armature winding is always in the same direction, enabling continuous rotation of the rotor.
The design and configuration of the armature winding, including the number of turns, wire gauge, and connection scheme, can influence the motor’s performance characteristics, such as torque, speed, and efficiency. Optimal winding design is crucial for achieving the desired motor performance in various applications.
In summary, the armature winding in a DC motor is responsible for producing the magnetic field that interacts with the stator’s magnetic field, resulting in the generation of torque and the rotation of the motor. It is a critical component that facilitates the conversion of electrical energy into mechanical motion.
