1results about How to "Reduce rotational load" patented technology

This utility model discloses a motor limiting device, including a motor rotor and a motor stator. The motor rotor and motor stator are rotatably connected. The motor rotor includes a limiting seat, and the motor stator includes a base. The limiting seat includes a first receiving groove, and the base includes a second receiving groove. The first receiving groove is located inside the second receiving groove. The bottom of the second receiving groove has an annular groove, and the end of the first receiving groove has a first protrusion. The first protrusion is rotatably disposed within the annular groove. The groove wall of the annular groove has an installation groove, and a locking member is disposed within the installation groove. The locking member and the first protrusion are matched and connected under external force to limit the relative rotation of the motor rotor and motor stator in the non-working state. This utility model, by having both the first protrusion and the locking member disposed inside the motor, helps to reduce the size of the motor, meets the design requirements of miniaturized motors, facilitates storage and carrying, and improves the overall aesthetics of the motor.
