Electrical Motor Repair

Repair Services and Features

Inline with JCI Industries Inc.’s commitment to provide one source for your repair needs we staff a full line motor repair shop. Our motor shop specializes in the maintenance and repair of low and medium voltage electric motors regardless of the make or model. Our shop foreman, technicians, and sales engineers all average over 25 years experience in the motor industry. Collectively our expertise is unmatched in the Midwest. Together with full engineering support and a comprehensive quality control program, these skilled technicians will reduce your downtime and operating costs.

JCI motor shop can provide expedited 24/7/365 emergency service along with on-site testing and preventative maintenance programs like MMP. Motor Management Program (MMP) consists of safe storage for critical spares, monthly rotation of each shaft, megger test of each motor, and documentation of findings. Reporting on all motors in MMP is available upon request. JCI continually invests in new technologies, such as PdMA®, to benefit our customers. PdMA® technology enables more proactive preventive maintenance during scheduled downtimes for our customers, who then avoid higher rush and emergency repair cost due to motor failure in the future.

JCI has standardized the use of inverter duty wire and insulation materials. This assures that all rewinds are compatible for use with Variable Frequency Drives. JCI provides AC/DC motor repair for fractional through 1500 horsepower motors, including: pump motors, brake motors, and slip ring motors. We consistently keep over 2,000 motors in stock. This on-hand inventory allows us to quickly address your motor needs. JCI is UL certified to repair explosion-proof motors for hazardous locations and is a member of the Electrical Apparatus Service Association. JCI, with the recent addition of the PEV Certification, can repair motors back to the original efficiency, making repair of motors a viable option over replacement. This ensures consistency in repairs and efficiency is maintained. JCI is the clear choice for your motor needs.

PDMA CASE STUDY – KANSAS CITY, MO

JCI performed PdMA motor circuit test on a 75 HP PD Blower Package motor that was tripping out at the Fishing River Wastewater Treatment Plant in Kansas City, Missouri.

Summary
Misdiagnosis caught with PdMA testing.
Unnecessary motor replacement avoided.

Problem
The 75 HP motor had continued trips of the circuit breaker tripped. Repeated operation resulted in breaker trips. The blower system was within the contractors warranty and resolution of the motors tripping was required.

Looking for the Root Cause
Initial efforts concluded that the fault was in the motor. Once notified of the situation, JCI meggered the motor and performed other tests to test the condition of the motor. JCI used a PdMA tester to verify the condition of the motor. The test indicated that both the motor and power circuit were in good condition with no apparent faults. The PdMA report determined the motor’s insulation system, power circuit and stator winding to be in good health. However, the Power Circuit Check revealed inferior wiring motor connection inside the motor junction box. JCI repaired the motor connection and the motor has not tripped since this was corrected.

Savings
JCI used off-line testing to verify the sound condition of the motor and power circuit. The savings from this action were substantial considering removal, installation and motor replacement expenses were prevented. Additionally, costly down time resulting from a misdiagnosis was avoided with the availability of the blower for the aeration of sludge for land application.
