In my previous article, I described the four most common methods for motor and pump control: input voltage, input voltage pulse-width modulation (PWM), external PWM, and 0–5V DC analog speed input.

When selecting the appropriate power switches for motor control applications designers are tasked with balancing performance requirements and total system costs. When system costs are the highest ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...

Sensorless motor control has primarily been applied to applications where the majority of the operating time is at higher electrical frequencies (mechanical speeds). This is due primarily to the fact ...

A Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. These devices, also known as ...

In today’s world, motors are ubiquitous, powering everything from household appliances to industrial machinery. The importance of optimizing motor control for energy efficiency cannot be overstated, ...
