Nidec B250T2C – The ACCU-Torq® motor series includes two variations: Totally Enclosed Blower Cooled (TEBC) and Totally Enclosed, Non-Ventilated (TENV). These motors are designed for applications requiring constant torque at or near zero speed. They feature a cast iron frame and end brackets, with corrosion-resistant paint for durability. The motors have an INVERTER GRADE® insulation system, regreasable bearings, and lifting provisions. TEBC models have an axial constant speed blower, while TENV models have a radial blower. Both variations offer constant torque operation from zero to base speed and constant power operation above base speed. They are suitable for various applications, such as packaging machinery, process lines, cranes, and hoists. The motors come with cast iron inner bearing caps, a shaft slinger for protection, and a shaft grounding ring. They have a class H insulation system, 1.0 service factor, and are available in different frame sizes. Conversion kits and a three-year limited warranty are also provided.
