Motor Speed Controllers

Model 210

Model 210_Manual


The compact Model 210 series three phase motor amplifier and speed controller modules are designed to directly drive 10 to 45 volt brushless DC motors at a continuous load current up to 2 amps . This series is ideal for speed control of sub-fractional HP motors in shaking, stirring, vibrating or other motion applications that require constant speed despite varying loads.

Features include:
  • Thermal-protected speed control.
  • Built in current-limiter for safe and reliable operation.
  • The drive provides power for the motor’s hall effect sensors.
  • Includes braking, reversing, and enabling inputs.

The Model 210 DC Motor Speed Controller adds a digital speed control board with LED display to the Model 210 Amplifier. Taken together, these two stackable and compact modules make the Model 210 a complete digital motor speed controller solution in a small footprint. The speed controller board mounts directly behind a panel and implements a complete user interface for displaying and adjusting motor speed. The amplifier board stacks directly behind the controller board and requires no additional mounting.

The two-board Model 210 speed control provides closed-loop regulation of the motor speed using the hall effect sensor outputs instead of expensive encoders. Motor speed is displayed (in RPMs, typically) on a 3 digit LED display, and is adjusted with ‘UP’ and ‘DOWN’ buttons. The front panel display can be scaled to units appropriate for the application.
