6200 Open-Loop Controller with Display

6200 Controller

Product Description

Magtrol’s Model 6200 is an Open-Loop 6200 Controller Dynamometer Controller designed for use with any Magtrol Hysteresis Dynamometer. The unit provides open-loop control of the dynamometer via an internal current regulated power supply. With a high-quality vacuum fluorescent readout, the Model 6200 displays torque, speed and mechanical power values of the motor under test. In place of mechanical power, it can also display auxiliary transducer readings via the ±5 VDC analog input. These displayed values can be stored internally or output via the RS-232 or IEEE-488 interfaces.

Pass or Fail Motor Testing

The Model 6200 comes with an easy-to-use motor testing Pass/Fail feature. This feature is ideal for quick Pass/Fail (Go/No Go) testing in production and incoming inspection applications. When the 6200 is operated in the Pass/Fail mode, one of three readings is used as the tested parameter: torque, speed or the auxiliary transducer. The two parameters not used are set with user-defined upper and lower acceptable limits. As the motor is loaded to the tested parameter value (for example, speed), the other two parameters (in this case, torque and transducer) are measured. Test results (for the other 2 parameters) are indicated with a “PASS” or “FAIL”, or the display can be toggled to show the actual values.
