Solid State Motor Controls

Solid State, Motor ControlsMotor soft starts are designed for AC induction motors. Soft starting is a method of reduced voltage starting that provides smooth, stepless acceleration that greatly reduces wear on power transmission components. Soft starting reduces motor in rush current by as much as 70%.

 

These Solid State Motor Controls have adjustable starting torque, ramp time and flex time. The flex time adjustment takes up the slack in conveyor systems and and also adjust the the starting ramp time on lightly loaded motors. Optionally available deceleration control adjusts perfect stopping utilizing three potentiometers that control instantaneous deceleration, deceleration time and the stopping point.

 

Solid State Motor Controls Features:

  • Solid state circuitry

  • Adjustable starting torque

  • Adjustable ram time and dual ramp

  • Adjustable current limit

  • Anti oscillation circuit

  • Adjustable flex time

  • Motor circuit protector or overload relay
