BRAKING RESISTOR DESIGNS AND APPLICATIONS

Introduction When a motor is driven by its mechanical load, such as in the case of a decelerating flywheel, the motor acts as a generator and the kinetic energy is converted into electrical energy. Often this surplus electrical energy, if it cannot be regenerate...

MOTOR PROTECTION IDEAL FOR PUMPS AND DIFFICULT ACCESS APPLICATIONS

Frequency inverters, which normally have switching frequencies of 2 to 20kHz, produce considerable common-mode (asymmetrical) noise. The fast switching of the DC voltage causes voltage peaks in motor cables and the longer the length of cable the higher the amplitude ...
