Product Details
The Baldor-Reliance motor is a 0.75HP, 1750RPM, DC motor with a 56C frame, model number 3428D, featuring a Totally Enclosed Fan Cooled (TEFC) design and an F1, N configuration. Key features include a TEFC enclosure, shunt wound construction, Class F insulation, and compatibility with NEMA Type K SCR control, allowing for a 20:1 constant torque speed range (except where noted). The motor is equipped with a NEMA C-face and removable base, with the exception of explosion-proof models, and a base that is welded on Type 3513D only. Motors with frame sizes NEMA 182 and larger include a thermostat (normally closed contacts) on the field winding, while the 35D, 75D, and 91D types do not feature dual mounting base holes. This motor is typically used in applications such as conveyors, printing, textile equipment, machine tools, and other equipment that require variable speeds with constant torque.
