Ms. Chen focuses on the magnetic fields that cause electromagnetic noise, the exciting forces they produce, and some measures to prevent noise during design.
    Motor noise classification

    The electromagnetic noise, ventilation noise and mechanical noise generated in the motor and their main vibration sources are summarized and discussed appropriately.

    The source of electromagnetic noise is the vibration and resonance in the iron core and its associated mechanical components caused by the alternating electromagnetic force caused by the various harmonic magnetic fields in the air gap of the motor. Mechanical noise is the periodic or aperiodic mechanical shock or vibration generated by the friction between the motor-related components.

    Aerodynamic noise includes broadband noise, whistle and whistle. Broadband noise is the noise generated by the rotation of the structural parts in the gas, and the gas is disturbed by the eddy current; the whistle is the noise generated by the relative movement between the stator and the rotor; the whistle is the noise generated by the resonance interference in the gap, the whistle Sounds and whistles are due to periodic fluctuations in the gas.

    what is noise

    From a physical point of view, noise is a combination of many incongruent or irregular residual sounds. Noise not only affects people’s work and rest, making people irritable and annoying; it even damages the health of guests, and even makes people deaf or cause many other diseases. At present, industrial noise has become 1 of the 3 major public hazards (sewage, waste gas, and noise) that pollute the environment. With the development of industry, in order to ensure a proper working environment and people’s health, certain measures must be taken to reduce the noise to an acceptable level. within the limit.

    The market demand for low-noise motors is actually a best example of our environmental protection and improved lifestyle. Once Ms. participated in a motor manufacturer, and the electromagnetic noise of the motor tested was particularly severe. Within 10 minutes, 2 people in the same group felt motion sickness. For noise, especially under the conditions of good motor operating environment, people began to pursue low-noise and high-efficiency motors, which is indeed a great progress in society.

How do electric motors generate motion and mechanical work?

Electric motors generate motion and mechanical work through the interaction of magnetic fields and the conversion of electrical energy into mechanical energy. Here’s a detailed explanation of how electric motors accomplish this:

  1. Magnetic Fields: Electric motors consist of a stationary part called the stator and a rotating part called the rotor. The stator contains coils of wire that are supplied with an electric current, creating a magnetic field around them. The rotor, on the other hand, typically has magnets or electromagnets that produce their own magnetic fields.
  2. Magnetic Field Interaction: When an electric current flows through the coils in the stator, it generates a magnetic field. The interaction between the magnetic fields of the stator and the rotor creates a rotational force, also known as torque. This torque causes the rotor to start rotating.
  3. Electromagnetic Induction: In certain types of electric motors, such as induction motors, electromagnetic induction plays a significant role. When alternating current (AC) is supplied to the stator, it creates a changing magnetic field. This changing magnetic field induces voltage in the rotor, which leads to the flow of current in the rotor. The current in the rotor produces its own magnetic field, and the interaction between the stator’s magnetic field and the rotor’s magnetic field results in rotation.
  4. Commutation: In motors that use direct current (DC), such as brushed DC motors, commutation is employed. Commutation is the process of reversing the direction of current in the rotor’s electromagnets as the rotor rotates. This is done using a component called a commutator, which ensures that the magnetic fields of the rotor and the stator are always properly aligned. By periodically reversing the current, the commutator allows for continuous rotation.
  5. Conversion of Electrical Energy to Mechanical Energy: As the rotor rotates, the mechanical energy is produced. The rotational motion of the rotor is transferred to the motor’s output shaft, which is connected to the load or the device that needs to be driven. The mechanical work is performed as the output shaft drives the load, such as spinning a fan blade, rotating a conveyor belt, or powering a machine.

In summary, electric motors generate motion and mechanical work by utilizing the interaction of magnetic fields and the conversion of electrical energy into mechanical energy. The electric current flowing through the stator’s coils creates a magnetic field that interacts with the magnetic field of the rotor, producing torque and initiating rotation. In some motors, electromagnetic induction is employed, where a changing magnetic field induces voltage and current in the rotor, leading to rotation. Commutation, in certain motor types, ensures continuous rotation by reversing the current in the rotor’s electromagnets. The resulting rotational motion is then transferred to the motor’s output shaft, enabling the motor to perform mechanical work by driving the load.
