Medium Voltage Motors
If you are looking for a large frame motor that can provide exceptionally long life, rugged durability and outstanding performance, remember, you can only get out of the motor what the manufacturer puts into it.
Applications:
Ideally suited for applications requiring heavy duty, large horsepower electric motors. Typical uses include pulp and paper mills, mineral processing, waste management facilities, lumber and wood processing mills, automobile manufacturing plants and other severe duty environments where medium voltage power is available.
Big Reason #1: A Superior Insulation System
Our medium voltage large frame motors have a premium Class F system, with stator and coils fully blocked, secured with surge rings and impregnated with epoxy resin varnish through vacuum pressure impregnation.
Big Reason #2: Longer Bearing Life
Only Lincoln gives you Inpro/SealTM bearing isolators standard on all our large motor drive end shafts – 5011 – 5013 Frame motors
Big Reason #3: It's Easy to Install Sensors That Can Prolong Motor Life
Our medium voltage motors, 400 HP and larger include 100 ohm platinum winding RTD's as standard. All end brackets are factory drilled for installation of bearing temperature sensors in the Field or through our factory modification center.
Big Reason #4: Physical Toughness Provides Ultimate Protection
Our motors have full cast iron construction - including frame, terminal box, end brackets and fan cover. Internal and external Epoxy finish.
Most of our 5000 frame motors have a 1.15 service factor for an added performance cushion. Many are available from stock. Our full load efficiencies are among the highest in the motor industry.
General Specifications:
Horsepower Range 150 to 700 HP
Voltage 2300/4000 Volts
Speeds 1800, 1200 and 900 RPM
NEMA Design B
Applications:
Ideally suited for applications requiring heavy duty, large horsepower industrial electric motors. Typical uses include pulp and paper mills, waste management facilities, lumber and wood processing mills and automotive manufacturing plants. Low voltage motors, 300 HP and smaller, conform to GM-7EH, Ford EM-1 and Chrysler NPEM-100 specifications.
