Yes, AC/DC is a band, but AC/DC also refers to motors. AC motors are found in power plants, chemical plants, municipalities, rubber, mining and cracker plants. DC motors are found in steel mill, rail, mining, plastic and shipboard applications. CMT can repair and refurbish AC and DC motors – anything from periodic bearing maintenance to […]
Today, CMT celebrates 36 years!
Medium voltage motors are manufactured for numerous industrial applications and can be found in power plants, steel mills, extrusion plants, press and forge plants, municipalities, chemical plants, rubber plants, oil and gas companies and in the military. CMT completely remanufactures all brands of medium voltage motors. CMT’s services include: in-depth evaluations with documentation, identifying core […]
— Voltage imbalance.: A 3.5% imbalance will drive a 25% temperature increase — Low and high voltage — Single phase of a three-phase machine — Lightning, surges and switching spikes — Ungrounded power systems — Loose electrical connections — Inverter settings — Restricted ventilation — Using the wrong lubricant and the wrong amount — Overload […]
What are the top tips to ensure motor life? Confirm you have the correct motor for the application and location. Read, understand and save a picture of the nameplate. Install and properly align the motor. Establish a preventative maintenance program. Relubricate with the correct type and amount of grease. And, if your motor fails, contact […]
Electric motor running hot? Temperature can create both mechanical and electrical drive failures. What causes temperature changes in a motor? Location, restricted ventilation, overload, imbalanced voltage, low voltage, duty cycle and inverter induced heat are some examples. CMT repairs AC and DC electric motors.

Cooling towers are found in major industrial and commercial facilities to extract waste heat into the atmosphere. Cooling towers are found in power plants, refineries and chemical plants. Smaller cooling towers are found at hospitals and universities. Most cooling tower systems have a motor driving a propeller shaft coupled to a gearbox. Some common problems […]
Ohio has been issued a “stay-at-home” order from Governor DeWine. CMT is excluded in this order because our work on power plant operations, food manufacturers, municipalities and commercial and industrial HVAC makes us essential. Our operations have not been disrupted, and we will continue business as usual. Here at CMT, we are continuing to monitor […]
This 1674 HP DC motor was recently remanufactured by CMT for a world-class pipe manufacturing mill. Also pictured is the armature, or rotating element from an identical motor. This armature will be rewound to an as-new condition with a new commutator and new coils. Once fully assembled, the motor will be returned for many years […]
