Find and buy variable speed drives from verified suppliers on IndustrySearch. A variable speed drive (VSD) is a device that controls the speed, acceleration and general operation of an electric motor.
Things to consider when buying variable speed drives:
Size your VSD - Your VSD should meet the motor’s voltage and horsepower rating, as well as maximum motor current at peak demand, to ensure reliable and long lasting operation.
Select constant or variable torque drive - For centrifugal applications such as a fan, a variable torque drive is more appropriate and energy efficient. For applications that require constant level of torque at all speeds such as a conveyor, a constant torque drive can be used.
Choose your VSD’s capabilities - Choose a VSD that meets your application’s requirements, from a wide range of control options such as speed control, forward & reverse operation, soft start, ramp up, ramp down operation, overload rating and vector torque control.
Consider specialized application requirements - Specialized requirements include IP rating, auxiliary motor cooling for low speed motor operation, remote operation monitoring, braking chopper modules, harmonic mitigation for equipment protection, and more.
