Tested/ working DC motor controller - Circuit board is marked MINARIK MA627-1 type 1, label on frame says Part Number 55129 for 1/4 HP shut motor 115V field, 115V armature, 6 amp line fuse (fast blow) input 115VAC 50/60 Hz.

Includes braking resistor as shown. Connections from left to right are as follows:

  1. field +
  2. 115V
  3. 115V
  4. common
  5. speed adj -
  6. speed adj +
  7. speed adj wiper
  8. Armature +

Note that the speed adjustment is already connected, just connect power to terminals 2 and 3, connect the motor armature to 4 and 8, and the field to 4 and 1. If you are using a permanent magnet motor connect the motor to 4 and 8 only. To brake the motor, provide a DPDT switch and connect the braking resistor across the armature in one position and connect the armature to the controller (terminals 4,8) in the other position.
