How Do I Test My DC Motor? - TigerStop

This procedure is for TigerStop products that use a DC motor: Currently includes TigerStop, TigerFence/CrossCut, and SawGears

 

Test Procedure Part One – (multi-meter required):

  1. Turn off power with the red rocker switch on the amplifier
  2. Unplug AC power cable
  3. Remove the 4 acorn nuts securing the end plate and remove the end plate
  4. The amplifier chassis slides apart into two pieces. Slide the cover part off
  5. There are three power leads coming from the motor.
    1. Red and Black – connected to the motor 1 and motor 2 terminals on the PCB
    2. Green Ground Wire – Connected to the ground lug on the amplifier chassis
  6. Set a multi-meter to test for ohms (the Ω symbol)
  7. Test the motor power leads in the following combinations
    1. Black and Red – the reading should be around 4 ohms for a TigerStop motor
    2. Black and Green – the reading should be O.L. (open line). Run this test while someone is pushing the carriage by hand
    3. Red and Green – the reading should be O.L. (open line). Run this test while someone is pushing the carriage by hand
  8. Record those readings.

Test Procedure Part Two (18-24v drill battery and 2 small paperclips or lengths of wire required)

  1. Touch the Red and Black motor wires to the positive and negative terminals on the drill battery.
  2. The motor should move
  3. Reverse the wires on the battery terminals
  4. The motor should move in the opposite direction.

Depending on the drill battery, it is sometimes useful to press paperclips or short lengths of wire into the spade connectors of the motor wires in order to allow contact with the drill battery terminals.
