Variable Speed Drives

Inverter Drives

Variable Speed Drives (VSD's) control the speed of main drive motors and have the capacity to alter the frequency of 3-Phase AC power entering into a 3-Phase AC motor. Also known as an Inverter Drive or Variable Frequency Drive, VSD's are an electronic power module which have the ability to alter the AC supply to an induction motor. This controllability on the output to the motor is then used to vary the motor speed and torque. VSD's can also be programmed to carry out other functions like dynamic braking, start/stop and speed up/slow down. In addition, they can be controlled by sensors or Building Maintenance Systems (BMS) to increase/decrease motor speeds or airflow to alter temperatures (particularly useful in refrigeration and air conditioning applications).

Are Variable Speed Drives cost and energy efficient?

Variable Speed Drives help to reduce carbon footprints as they help you to monitor and reduce the consumption of energy used by as much as 50%. This monitoring and reduction in the consumption of energy used will help to reduce fixed energy costs.
