Drive Output Chokes or Load Reactors

Output chokes /Output reactors which are also known as Load reactors are used at the load side in front of the motor when the cable length is long . It is done mainly to protect the motor from capacitance of the cable length . The drives generates a high frequency PWM three phase output and noise spikes are generated on the leading edge of the signal . These noise signal gets amplified due to long cable length and additional capacitance of the cable . This results in high voltage in motor which results in insulation failure of the motor.

AMPS Tech are experts in designing of output chokes or load reactors irrespective of length of the cable . If the cable length increase more than 500ft Magnetic and Controls designs special dV/dT filters to protect the motor . Load reactors or Output chokes are connected in series between the controlled and the motor.
