Vibratory Motor Repair and Rewind Service
Most vibratory equipment OEMs and motor repair shops are not qualified to repair vibratory motors. Sending your motors to them– or attempting to repair them in-house– can lead to poor performance and premature failure. Also, in many cases it will void the manufacturer's warranty.
We recommend that vibratory motors always be serviced by a shop like our Malvern, PA, Service Center, one that specializes in vibrator repair and is fully qualified. (Qualified Service Centers use only genuine replacement parts, including manufacturer specified specially formulated grease.)
In short, if your vibratory motor needs repair, bring it to us with confidence. We're ready and able to help.

FAQs
Q: Will low voltage affect my vibratory motor? Read more »
A: Yes. Operating a Vibratory Motor with a voltage that is lower than nameplate voltage (≤ 10%) will alter the Motor’s performance. Some performance characteristics will change slightly, while others, such as amp draw, will change dramatically. A Vibratory Motor is classified as a "heavily loaded motor" (power factor is high), especially at start-up. The amount of power a Motor draws is a direct correlation between voltage and amperage (V = IR). If Voltage (V) is low, then Current (I) must increase to provide the same amount of power because the Resistance (R) is fixed. As Current increases, heat builds in the Motor. Without corrective action, the heat will damage the Motor’s windings and bearings. The extent of Motor damage is based on the frequency and duration of the low-voltage abuse.
Notable facts about Low-Voltage supply to Vibratory Motors:
- Single-phase Vibratory Motors are less adversely effected by low voltage than three-phase Vibratory Motors.
- Vibratory Motor efficiency drops significantly with low voltage, resulting in more cost to operate and a shorter motor life.
- Ironically, the power factor improves with low voltage.
- As Voltage decreases, the Current will increase in the same proportion. This will cause the Motor’s nameplate Full-Load Amp (FLA) Draw to be exceeded.
- Low Voltage reduces starting torque, which in turn increases stress on the windings due to heat build-up.
Low-Voltage operation will shorten the life of a Vibratory Motor. The downtime of this critical equipment can be avoided by ensuring that the proper voltage is supplied to all Vibratory Motors. Close
Q:Will high voltage affect my vibratory motor? Read more »
A: Yes. Operating a Vibratory Motor with a voltage that is higher than nameplate Voltage (> 10%) will alter the Motor’s performance. Many users mistakenly believe that because Low-Voltage increases the amp draw, that high voltage will lower the amp draw. In reality, High-Voltage will put the magnetic portion of the winding into saturation.(Motor Saturation, simply stated, means the Motor needs a larger magnetic circuit to operate.) Saturation causes the magnetic-iron portion of the winding to be pushed beyond its limits which in turn increases Current. As Current increases, heat builds in the Motor. Without corrective action, the heat will damage the Motor’s windings and bearings. The extent of the Motor damage is based on the frequency and duration of the high-voltage abuse.
Notable facts about High-Voltage supply to Vibratory Motors:
- High voltage causes in-rush Current (at Start up) to exceed "safe" limits.
- High voltage causes Vibratory Motor efficiency to drop resulting in more cost to operate and a shorter motor life.
- 1200 and 900-RPM Vibrators are more sensitive to high voltage supplies when compared to 3600 and 1800-RPM Vibrators. The lower speed Motors are damaged more rapidly when being supplied high voltage.
- Single-phase Motors are more adversely affected by high voltage than three-phase Vibratory Motors
- Power factor of a Vibratory Motor quickly drops with high voltage.
- High voltage drives up amperage and heat damage of even lightly loaded Motors because a Vibratory Motor is a heavily loaded Motor, it suffers even greater heat damage as voltage supply rises.
High-voltage operation will shorten the life of a Vibratory Motor. The down-time of this critical equipment can be avoided by ensuring that the proper voltage is supplied to all Vibratory Motors. Close
Q: What operational parameters need to be inspected during initial start-up of a rotary electric vibrator? Read more »
A: Make sure the power supplied matches the nameplate requirements. Assure the mounting hardware is properly sized, is minimum Grade-5, and is torqued to the manufacturer specifications. Verify the motor starter is properly sized and set to protect the Vibrator during operation. While a slight bearing noise is normal and should be expected, excessive noise during operation could indicate a problem. Upon start-up, the amp-draw line current could exceed the nameplate value, but this should drop quickly after the motor is broken-in. If, after a few hours, the amp-draw still exceeds the nameplate value, there could be problems with the mounting or the Vibrator, and the Vibrator must be shut-off until the issue(s) is resolved. Never permanently operate the Vibrator above the amp-value shown on the nameplate. After 15-minutes, and then again after 8-hours of operation, re-torque the mounting hardware. After 8-hours, verify the amp-draw is at or below the nameplate value.

Q: How often should a rotary electric vibrator be lubricated? Read more »
A: Typically every 2000-hours. It is important to use only the specified type and amount of the manufacturer recommended grease. Use of non-recommended grease and/or over- or under-lubricating the Vibrator will result in shorted Vibrator life. Vibrators in some specific applications, and Vibrators exposed to excessive heat and/or high wear applications will require more frequent lubrication.

Q: Can rotary electric vibratory motors be rebuilt mechanically and electrically? Read more »
A: Yes , but it depends on the size of the Vibrator. All Vibrators, no matter the size, can have the bearings replaced in the event of a mechanical failure, as long as it is cost effective. Only factory supplied bearings should be installed and the manufacturer’s recommended type and quantity of grease must be used. In the event of a stator failure, some stators are replaceable. The ability to replace a failed stator depends on the OEM’s method of installation. If the stator has been installed in the housing with epoxy, it is probably not cost effective to replace or rewind the stator. If the stator has been press fitted into the housing, it is usually cost effective to replace or rewind the stator. Rewinding of a stator should only be performed by qualified electrical rewind shops that are both aware of and follow the special requirements of a stators used in Vibratory Motors.

Q: Can a rotary electric vibrator be test run with the weights set at zero percent or with the weights removed? Read more »
A: No. Do not test run a Vibrator with no centrifugal load on the bearings. Vibratory Motor bearings are oversized to handle the extreme loads they encounter during operation. Operation of the Vibrator without a centrifugal weight load will cause the bearings to skid (rather than rotate) and build-up excessive heat which deprives the bearings of lubrication. This bearing damage occurs rapidly when no bearing load is used during testing. Close
