Abstract

The invention relates to a small high-speed three-phase asynchronous motor with a target speed of 98,000 rpm and a power of 1.5 kilowatts. It adopts 18 slots, 2 pole slots, and very integer slots. It is characterized in that the stator core and the winding on the rotor core The form is double-layer winding; the motor air gap between the stator core and the rotor core is 0.2mm; the number of stator slots is 18; the rotor core adopts a punched rotor, and the rotor slot adopts a closed round bottom slot structure. The number of slots is 16, the slot fill rate is 80%, the thickness of the rotor core is 55-65 mm, and the material of the guide bars embedded in the rotor core is cast aluminum. The invention improves the performance of the motor and reduces energy consumption by optimizing the parameters of the motor multiple times, and realizes low cost, high efficiency and low loss of a small ultra-high-speed three-phase asynchronous motor. The invention is suitable for small and medium-sized steel rolling equipment, various metal cutting machine tools, light industrial machinery and other mechanical equipment.

Description
