hardware. Tighten as required. 

Excessive noise 

Defective bearing 

Replace both bearings in accordance with 
Bearing Replacement. 

Motor turns too 
slowly 

Incorrect supply 
voltage or line 
frequency 

Check that supply voltage and line frequency 
agree with motor data plate. Frequency must 
be within ±1Hz. 

No electric power to 
one motor 

Check that supply voltage is connected to both 
motors. 

Motors not 
synchronized (dual 
motors only) 

Incorrect electrical 
connections 

Confirm that electrical connections are in 
accordance with the instructions in this section. 

* Derrick vibrator motors run with higher surface temperatures than standard industrial motors. 
Refer to the maximum temperature rise indicated on the motor data plate attached to the motor 
case or the motor data sheet included in this manual.
