Industrial Drives are used to control the speed of various sizes of motor. AC (Alternative Current) are also known as VFD’s (Variable Frequency Drives)/VSD’s (Variable Speed Drives) or ASD’s (Adjustable Speed Drives) whist DC (Direct current) Drives are used to convert AC supply into DC when applications require constant speed due to their high start-up torque.Servo Drives, Sometimes known as amplifiers can be both AC or DC, and receive information back from the motor and adjusts accordingly enabling high speed, high accuracy commands.
Popular Drives include Allen Bradley PowerFlex, Siemens Sinamics, Lenze, Yaskawa, Danfoss, Control Techniques UniDrives, Leroy Somer, Elau PacDrives
