Static Testing Continuity Test
r:;J 1Check motor with an ohmmeterCalibrate ohmmeter on high ohms scaleGround one ohmmeter lead to the motor frameMove the other ohmmeter lead between the red and green leads from the motor Ohmmeter should indicate infinity
If continuity is indicated; brushes, wiring or armature might be groundedRefer to Electric Motor Servicing, Page 5-81Connect torque wrench to the motor shaftActivate the test circuit and note the voltage, torque and current drawNo Load Test 2Connect the test circuit, and note the amperage and voltage readingsrJl 3Use vibration or mechanical tachometer to measure the motor RPM4Compare the values, as tested, to the chart belowStall Torque Test f.il 1Connect torque wrench to the motor shaftActivate the test circuit and note the voltage, torque and current drawNo-Load Test Model 12 Volt 12 Volt H.T24 Volt 24 Volt H.TRPM 2000-2175 1600-1800 2475-2600 1615-1785 Amps (Max Voltage (Min 10.5 10.5 22 22 Stall Torque Test Torque (Min 31 inIbs38 inIbs31 in Ibs65 inIbsAmps (Max 105 90 90 100
