Having an electrical motor stop working can bring your operations to a halt. For industrial equipment, small motors, commercial HVAC systems, or household appliances, prompt professional motor repair is key to restoring things smoothly. Here is what you need to know about servicing and repairing your electric motors by qualified technicians.
Diagnosing the Issue
Start the repair process by contacting a reputable motor service company to have them properly diagnose the issue. Be prepared to describe any symptoms or problems in detail. Technicians will visually inspect the large or small motor, test it, and check components to pinpoint where the failure occurred and why.
Common problems include burnt windings, bad bearings, dirt buildup, stuck rotor issues, and overload failures. Professional diagnosis is crucial to identify the root cause.
Repair vs. Replacement
For small household appliance motors, replacement is often more cost-effective than repair. However, industrial-size motors can be extremely expensive to replace.
Professional motor repair experts will assess whether fixing or replacing parts is better based on factors like motor size, type, brand, age, warranty status, parts availability, and service cost.
Rotor and stator rewinds or replacements are common for burnt windings. Technicians may also recommend replacing bearings, switches, starting capacitors, or other components.
Disassembly and Cleaning
To access internal components for repair, motors need partial or full disassembly. Technicians methodically disassemble and tag parts to keep proper orientation. A thorough cleaning removes built-up dirt, debris, and burnt insulation.
Sandblasting or chemical cleaning prepares parts for inspection, rewinding, replacement, or other service procedures. Proper disassembly and cleaning are required before accurate troubleshooting and repairs can occur.
Technicians will rewind or replace the copper wiring in the rotor and stator sections for motors with burnt windings. Insulation is replaced, and new wire coils are carefully wound. The level of disassembly, cleaning, and rewinding required depends on the motor design and the extent of damage.
Motors may also be refurbished with new bearings, brushes, commutators, sleeves, and other parts that wear over time and use. Refurbishing restores performance, efficiency and longevity.
Reassembly, Testing, and Installation
The same care and attention to detail required for disassembly is followed in reverse for proper reassembly. All parts must be realigned and components replaced exactly as oriented before service.
Once fully reassembled, the motor’s operation, electricity inputs, functionality, and performance undergo rigorous testing. The serviced motor is then ready for final installation and use once it passes all testing inspections.
