Supported Motor Types (Electric Motor Simulation Toolkit)

The Electric Motor Simulation Toolkit allows you to simulate the following types of electric motors.

• AC induction motors (ACIM)
• Permanent magnet synchronous motors (PMSM)
• Switched reluctance motors (SRM)

ACIM

An ACIM is a type of electric motor that has a stationary stator outside and a rotor which spins inside. By supplying alternating current to the stator, the ACIM uses the electromagnet of the stator to generate current in the rotor and produce torque. The stator is a hollow metal cylinder with slots for coils of wires. The rotor consists of metal bars which have end rings at both ends to form short circuits. The following figure illustrates a typical ACIM.

PMSM

A PMSM is a type of electric motor that utilizes permanent magnets in the rotor. The poles of a PMSM indicates how many even numbers of magnet poles that the rotor has. The following figure is an example of a typical PMSM. This motor has four permanent magnets on the rotor, as shown in the figure.

SRM

An SRM is a type of electric motor that produces torque from a slight misalignment of poles on the rotor with poles on the stator. The rotor tends to align itself with the stator to maximize the inductance of the stator, while the stator is consequently energized to force the rotor to rotate. The phase of the SRM indicates the number of pole pairs in the stator. For example, the following figure illustrates a three-phase SRM. The stator of this motor has three pairs of poles.
