Treadmill Load Testing – Motor Torque and Current Draw
Learn how professionals perform a load test on a treadmill to diagnose motor torque and high friction issues by measuring the current draw (amps).
What is Load Testing and Why is it Done?
Load testing is a diagnostic procedure to measure how much electrical current (amps) a treadmill motor draws under different conditions. It helps differentiate between a weak motor and high friction.
The Tools: Using an AC/DC Clamp Meter
This section introduces the amp clamp, the professional tool used to safely measure current draw without disconnecting wires.
Measuring No-Load vs. Loaded Amp Draw
Explaining the process: a technician measures the amp draw with no one on the belt, and then again with a user on the belt. The difference between the two readings is key.
Interpreting the Amp Draw Readings
This section provides baseline figures for normal amp draw and explains what high readings indicate (e.g., high friction, failing motor).
Differentiating a Weak Motor from High Friction
How the test results can definitively tell a technician whether to recommend belt/deck lubrication or a new motor.
