Silencer® Series Drive Electronics

2-QUADRANT SPEED CONTROLLERS FOR BRUSHLESS MOTORS

Silencer® brushless controllers are available in a variety of voltage and current ratings. All controllers have generous terminal blocks to facilitate ease of wiring and they are designed for ease of mounting in a small envelope, requiring minimal space in a cabinet / enclosure.

Silencer drives are compatible with Silencer Series Brushless DC Motors. Silencer motors are available in sizes 12, 17, 23, 28, 34 and 42 in standard frames with 1.2 to 4.15 inch diameters. They offer speeds up to 20,000 rpm and continuous torques ranging from 1.2 to 519 oz-in. Standard options include gearheads, resolvers and encoders.

Features

  • 2-quadrant speed controllers for brushless motors
  • Feedback using Hall effect sensors
  • Motor speed is set by either an internal or external potentiometer
  • Motor rotation direction can be present by the direction control input; the controller output stage can be activated and deactivated by the disable control input
  • Maximum constant current can be adjusted via an on-board potentiometer
  • Internal thermal cutoff prevents heat overload
  • Very high efficiency is achieved by using POWER-MOS-FET technology in the controller output stage
  • Efficient PWM speed control
  • Operating temperatures from -10 to 45°C and storage temperatures from -40 to 85°C
