Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

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 ...

Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

The DynaMotor from DynaMotors Inc., Warrensville Heights, Ohio, uses optically controlled solid-state switches embedded in the rotor windings to control current and, thus, torque, making the motor a ...

This triac-based 220V AC motor speed controller circuit is designed for controlling the speed of small household motors like drill machines. The speed of the motor can be controlled by changing the ...

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, ...

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 ...

Designed to control speed, the N series includes single-pole, single-throw switches suitable for use in professional power tools. These include drills, drivers, hammer drills, shears, and nibblers.
