What does AC or DC Motor mean?
AC and DC referes to the type of Motor / Dive. AC is alternating current, (i.e mains electric) DC is direct Current, (i.e. vehicles). Originally devices requiring a variable speed motor utilised a DC Motor and electronics. As drive technology evolved AC Motors were utilised for these applications. Modern AC Drives have become far less expensive and offer a host of control and feedback parameters to improve motor performance, reliability, protection and control. Over the last few years Servo and Vector units have been developed which are frequently utilised in industrial control applications. Generally domestic grade treadmills utilise DC motors as these do not require Inverters which represent additional cost. Commercial treadmills frequently have AC motors driven by industrial inverters. It is often the case that a machine driven by an AC drive will not require such a large motor as a DC machine. All commercial machines should be A.C. driven. A DC machine will be substandard for comme
