Electromagnetic Analysis

---

Electromagnetic analysis calculates the magnetic field and currents of an electric motor. This analysis is used to determine the motor's torque, power, and efficiency.

Ansys Maxwell is one of the most powerful software packages used for electromagnetic analysis of electric motors. Maxwell can accurately calculate the magnetic field and currents using a 3D model of the motor.

Electromagnetic analysis plays an important role in the design of an electric motor. It can be used to optimize the motor's performance and efficiency. For example, electromagnetic analysis can be used to:

• Increase torque and power output by optimizing the motor's magnetic field.
• Increase efficiency.
• Reduce noise and vibration levels.

Acoustics Acoustics is the science of sound wave production, propagation, and perception. In the design of electric motors, acoustic noise and vibration are an important consideration.

Electric motors can produce vibrations from magnetic fields. These vibrations create sound waves around the motor. These sound waves determine the motor's noise level.

To reduce the noise level of electric motors, acoustic analysis can be used. Acoustic analysis calculates the vibrations of the motor. These calculations can be used to make design changes to reduce the motor's noise level.

Ansys Sound is a powerful software package used for acoustic analysis of electric motors. Sound can accurately calculate the vibrations and sound levels using a 3D model of the motor.

Vibration Vibration is the oscillation or shaking of an object. Electric motors can produce vibrations from magnetic fields. These vibrations can cause stress and deformation in the mechanical parts of the motor.

To ensure the strength and reliability of electric motors, vibration analysis can be used. Vibration analysis calculates the vibrations of the motor. These calculations can be used to make design changes to reduce the motor's vibration levels.

Ansys Mechanical is a powerful software package used for vibration analysis of electric motors. Mechanical can accurately calculate the vibrations and stresses using a 3D model of the motor.

Ansys Sound Ansys Sound is a powerful software package used for acoustic analysis of electric motors. Sound can accurately calculate the vibrations and sound levels using a 3D model of the motor.

Ansys Sound plays an important role in the acoustic design of electric motors with the following features:

• Multiphysics simulation: Sound can perform acoustic analysis by taking into account the electromagnetic, thermal, and mechanical properties of the motor. This provides more accurate and comprehensive results.
• Fast finite element solution: Sound can quickly perform acoustic analyses using fast finite element solution. This speeds up the design process.
• Acoustic optimization: Sound can suggest design changes to reduce the motor's noise level using acoustic optimization.

Example Application

A manufacturer of electric motors was working on a new electric motor design. To reduce the noise level of the motor, the manufacturer used Ansys Sound.

Analyses using Sound showed that vibrations from the motor's magnetic fields were increasing the noise level of the motor. To reduce the vibrations, the manufacturer redesigned the motor's magnetic fields.

The new design was re-analyzed using Ansys Sound. The analyses showed that the new design reduced the noise level of the motor by 20%.

This example shows how Ansys Sound can be used in the acoustic design of electric motors.
