8.3 Motor Noise – Turntide Knowledge Base

1. Check that the wires are connected per wiring diagram

2. Check belt alignment between pulleys. Improper alignment can cause abnormal noises.

a. Make sure the motor pulley is secured to the motor shaft, if it is loose, it can misalign the belt.

3. Make sure the motor is firmly secured to the motor mounting plate. A loose motor can cause vibrations which can make weird noises.

4. Noise during startup can be caused by an older firmware on the motor controller.

a. Make sure that the motor controller has the latest firmware installed.

5. Noises combined with vibration that start and stop, check the data cable for continuity.

a. Make sure that the data cable is properly connected and secured on both ends, vibrations can occur if the cable is loose.

6. Motor terminal box is one of the largest sources of audible noise for our motor.

a. Make sure that locknut is not securing it tightly to the NPT fitting it will vibrate more and make more noise.

7. Adjusting the speed of the motor can decrease motor noise.

a. The speed can be increased or decreased in increments of 10 RPM while measuring dB level to find the RPM that provides the lowest dB level.

8. If none of these steps resolve the issue, escalate to engineering and replace the motor.
