Servo motor repair and testing by specialist engineers
Servo motor repair and testing requires a careful blend of electrical, electronic and mechanical skills – attributes that our specialist engineers are well qualified to bring to the task.
At Westin Drives we understand how important a servo motor is to your industrial processes. Equally important, we understand their quirks and complexities.
Our sister company, Quality Servo Motor Repairs, completes many servo motor repairs each year in our Huddersfield workshop. Motors are fully serviced and tested to ensure repairs are cost effective and of the highest quality.​
We have a policy of continual investment in test equipment, as new and more complex types of servo motor are booked into our service centre week by week.
​
Besides basic problems like slow starting, rotation failure, overheating, abnormal noise or erratic operation, there are some specific industry causes:
​
+ Cleaning machines in food production processes by jet wash, steam hose or caustic solutions can cause water and fat ingress, corrosion of the motor casing and contamination of the feedback device.
​
+ During paper processing, dust can gather around the oil seal and erode the drive end shaft. The motor shaft is frequently placed under extreme accelerative torque. Bearings and bearing housings are often compromised.
​
+During metals or glass processing, oil, coolant and/or anti-weld fluid can get into motor windings. Oil seal wear in drive end of motor shaft.
CASE STUDY: A sticking brake
The production line at a upholstery fillings factory had stopped due to the failure of a large servo motor, which was sent to us for repair.
Upon inspection, it was found the brake was sticking on because the bearing had collapsed.
We carried out a repair and refurbishment and returned the motor to the customer the following day. It was reinstalled and operations were resumed with a minimum of lost time.
