In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

It is no secret that any equipment that either heats or cools is coming under great scrutiny as governments increasingly legislate efficiency standards. In particular, washing machines, air ...

Today's motors are increasingly driven via electronic controls, which offer better control of speed, position, and torque, as well as much greater efficiency, rather than via direct connection to ...

To better understand the origins of noise, we need to think about how the rotation movement takes place. When a stepper motor performs a step, it does not stop immediately but continues to move ...

How the challenges of electric-motor control design can be overcome using digital twins in all design and test phases. How automated testing within a continuous and integrated toolchain is able to ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...

The air conditioner compressor motor driver as shown in Fig.1 utilizes advanced model-free predictive control technology, ensuring efficient and stable operation under varying load conditions.

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...
