Variable-speed drives are a powerful yet underused tool for boosting energy efficiency, reducing emissions, and optimizing ...

Learn how and why Fallbrook Technologies is working on NuVinci continuously variable planetary-assisted superchargers on Motor Trend's WOT.

It is this variable output that is used to control motor speed, torque, or position. PWM is used in modern adjustable frequency drives because it is efficient.

Five high-efficiency, variable-speed electronically controlled motors (ECM) are designed for residential and light commercial air-moving applications. The motors utilize advanced technologies to ...

This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller.

The Ultratech™ variable-speed motor is a four-wire electronically commutated motor with two-way communication. The motor receives commands from the furnace system control board, executes the command, ...
