Figure 1: Permanent Magnet Synchronous (PMS) motors are commonly used in industrial applications because they natively offer higher torque at lower speeds

Motors come in many forms. They range from stepper motors that are often used in precision positioning applications to the large Alternating Current Induction (ACI) motors often employed to deliver high torque for industrial mixing and processing. Very often, the choice of motor is not just determined
