[0002] At present, the switched reluctance motor is a new type of speed-regulating motor. The speed-regulating system has the advantages of both DC and AC speed-regulating systems. The advantages of high efficiency and high system reliability within the range are widely used in various fields. The switched reluctance oil pump motors on the market cannot output torque stably when starting, the torque is not very uniform, and the rotor assembly has no speed in the entire speed range. It has a fairly uniform torque curve, and has a relatively large impact on the motor. When it is applied to the power system of a forklift, it will produce a large noise, the service life is not long, and it is easy to damage

Abstract
The invention discloses a switched reluctance oil pump motor and a forklift power system applying the same. The forklift power system comprises a switched reluctance oil pump motor which is connectedwith a gearbox. The gearbox is connected with a driving shaft and a brake. The switched reluctance oil pump motor comprises a stator assembly and a rotor assembly, the number of poles of the stator assembly is 12, an outer diameter of the stator punching sheet is 180 mm, an inner diameter of the stator punching sheet is 103.6 mm, a yoke thickness of the stator punching sheet is 9.4 mm, eight rotorteeth are evenly arranged on a circular outer portion of a rotor punching sheet, the outer diameter of the rotor punching sheet is 103 mm, and the inner diameter of the rotor punching sheet is 36 mm.By reasonably designing a groove-shaped size of the punching sheet, magnetic flux density on the punching sheet is uniformly distributed, a torque waveform is smooth when the motor is started, stability of the motor is improved, and impact on the motor is reduced so that the forklift power system applying the switched reluctance oil pump motor is more stable in operation, longer in service life and higher in accuracy.
