In controlling this range of motors, your design requirements move from crudely chopping the supply voltage for single-phase motor speed control to providing constant torque control for a three-phase ...

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 ...

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 ...

NEC Electronics’ (distribution: Gleichmann Electronics) two new 3-phase control device families, V850E/IF3 and V850E/IG3, open up all kinds of new application possibilities. Key features of these ...

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 ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

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 ...
