The voltage and other specifications are first, followed by speed and model number. In the picture shown above, you’ll see “24V” defining the motor voltage, then “60Hz” for the frequency. The “6W” indicates the wattage and the “60RPH” indicates the speed. Other motor speeds may be listed as “1RPM” or “1RPD”. “38572R” indicates the model number of the motor - we’re looking for a 5 digit number ending in “R” or “L”. The “R” and “L” indicates which direction the motor turns. We may also ask you what color wires the motor has - in this case, blue.

Synchron motors often display the same model number for different voltages.

This is why it’s important to note the voltage.

Many Synchron motors look alike. In order to determine the correct replacement motor or retrofit kit, we’ll ask you information about the motor you are replacing, including voltage, speed, and model number.

                             Here’s how to locate that information on your motor:

Synchron motor replacement p/n 39154R - SUB

 for the obsolete or difficult to find 39154R motor.

(blue wires)

 This is another quality substitution motor that we have developed to keep you damper going and not require full damper replacement. Quality Synchron motor has very similar specification to the 39154R motor you are replacing.


Installer will need to drill out end of hollow aluminum damper shaft about 1/4 inch with a 21/64, 11/32 or similar size bit, to allow brass nose on shaft to enter shaft so motor will fully seat on damper. A 21/64 drill bit will be supplied with this motor. 

Since the shaft material is both aluminum and already hollow, this is typically not difficult if carefully done.

Another method to mount the motor is to install washers under the mounting screws of motor, to elevate the motor so the brass nose piece does not interfere with the damper shaft. While his eliminates the need to drill  the end of the shaft, it may cause a shorter life span of the motor, especially on larger (12 inch and above) dampers. The washers are NOT needed if the drilling method described above is used. Use the drilling method if practical.Also look at our Kit 4 Belimo replacement Motor for this application.
