T & N Electric Motor Exchange in Baltimore: Industrial Motor Repair and Rewinding
T & N Electric Motor Exchange is a motor repair and rewinding shop serving Baltimore's industrial and commercial sectors, located on the city's east side and operating since the 1980s as a specialist contractor for electric motor rehabilitation rather than general electrical work.
What T & N Electric Motor Exchange actually is
This is not a residential electrician service. T & N focuses on electric motor repair, rewinding, and testing for industrial equipment, HVAC systems, pumps, and machinery. The shop accepts motors from contractors, facility managers, and manufacturers, diagnoses mechanical and electrical faults, rewinds burned-out or damaged coils, replaces bearings and seals, and pressure-tests repaired units before return. The work requires EPA compliance for refrigerant handling on some jobs and produces lead-bearing solder waste that the shop manages under hazardous materials protocols. Scale ranges from fractional-horsepower motors (under 1 HP) used in small equipment to industrial three-phase motors exceeding 100 HP. This is specialized trade work, not panel upgrades, outlet installation, or emergency residential calls.
Services and pricing
T & N charges diagnostics at a flat rate (typically $25 to $75 depending on motor size and fault complexity; call to confirm current fees), then quotes repair cost based on labor, rewinding materials, and replacement parts. Rewinding a small single-phase motor runs $150 to $400; a mid-range three-phase industrial motor, $400 to $1,200; large industrial units can exceed $1,500. Bearing replacement, seal work, and pressure testing are billed separately. Rush turnaround (24 to 48 hours) carries a 20 to 30 percent upcharge. The shop accepts warranty returns on repaired motors and typically guarantees work for one year from completion, though terms vary by job scope. Payment is due upon pickup unless a standing account is established with regular commercial customers.
How it compares to other Baltimore electricians
T & N is not a direct competitor to full-service electricians like Bates Electric or Roto-Rooter's electrical division, which handle residential and commercial panel work, circuit installation, and code-required inspections. Those firms refer motor-specific jobs to specialists like T & N because rewinding requires equipment and certifications outside the scope of general contracting. If your motor is failing, T & N will diagnose it; if your panel needs upgrading or your house needs new circuits, call a licensed general electrician. T & N's advantage is depth: the shop has test stands and winding equipment on-site and employs technicians trained specifically in motor failure modes, whereas a generalist electrician would send the motor out, adding days and markup to your bill. Conversely, if you need same-day residential service on a weekend, T & N is closed and not equipped for it.
Who it suits and who it does not suit
Choose T & N if you operate equipment with electric motors that have stopped working, overheated, or tripped repeatedly. This includes HVAC contractors managing customer units, facility managers at warehouses or manufacturing plants, pump service companies, and equipment rental firms. Do not call T & N for home electrical repair, outlet installation, lighting design, or emergency service. The shop serves business hours during standard commercial schedules and requires you to deliver or arrange pickup of the motor; they do not perform on-site work.
What the first visit involves
Bring the motor (or arrange to have it picked up by courier for a fee) along with any documentation on voltage, horsepower, speed rating, and known failure symptoms. T & N will visually inspect it, test it on the bench, and call you with a diagnosis and flat quote. If you approve, the shop schedules repair into its workflow. Turnaround is typically 5 to 10 business days for standard rewinding; rush work shortens this but increases cost. You pick up the repaired motor or have it shipped. Some customers establish standing accounts and receive invoicing rather than prepayment.
Hours, location, and logistics
T & N operates Monday through Friday, 8 a.m. to 5 p.m., closed weekends and major holidays (verify holiday schedules by phone). Street parking is available at the site. The shop does not offer loaner motors, so plan for downtime; some customers keep spare motors on hand or arrange temporary rentals from equipment suppliers during repairs. Delivery and pickup services are available for an additional fee.
T & N holds a solid niche in Baltimore's industrial service ecosystem because rewinding is a specialized skill that saves money compared to replacing motors outright, especially for larger units. It is the place to send a failed motor, not the place to call for electrical problems in your home.
