AC/DC Motors

RL Electric, as an independent rotating equipment service company in Canada, offers comprehensive services for AC/DC motors used in various industries. With over three decades of experience in AC/DC motor repair, we have evolved our capabilities to meet the diverse needs of our clients. Our AC/DC motor services include:

  • All voltage ranges: We handle LV, MV, and HV motors, with a maximum voltage range of 4,160 V.
  • Power range: We can work on fractional power motors up to high-power motors with ratings of up to 2,500 HP (2 MW).
  • Standard and custom-made motors: We provide services for both standard motors and custom-made motors, with or without OEM support/designs.
  • Wide range of manufacturers: We have partnerships with reputable OEM motor manufacturers (TECO / Westinghouse, Us Electric, ABB Baldor, Marathon, Leeson, Ohio, NIDEC, TechTop, WEG, Fasco)
  • Our team of engineers and technicians is skilled in handling all types of AC motors. This includes synchronous and induction motors, both single-phase and three-phase motors, and different rotor designs such as phase-wound and squirrel cage. We are experienced in working with motors of different pole configurations. 

For DC motors, we have the expertise to handle different winding types (series, shunt, and compound), excitation configurations, and brushed and brushless DC motors of various sizes. We can address electrical and mechanical issues in DC motors, identify and rectify problems related to commutators, and provide comprehensive maintenance and repair services.

With RL Electric, you can trust that your AC/DC motors will receive expert attention and high-quality service to keep them operating at optimal performance levels.
