摘要: A motor for use with an elevator system may include a housing, a motor shaft surrounded by the housing and having at least a first end extending outward from the housing, a motor body arranged around a central portion of the motor shaft and positioned within the housing, at least one sheave positioned at the first end of the motor shaft and rotatable with the motor shaft, and a braking system positioned at a first end of the housing. The braking system may include a brake rotor connected to and rotatable with the motor shaft and closing an axial opening at the first end of the housing, a brake shoe positioned at the first end of the housing, and a brake actuator configured to selectively move the brake shoe between a brake position in which the brake shoe is in contact with the brake rotor to resist rotation of the motor shaft and a rotation position in which the brake shoe is free from contact with the brake rotor.

摘要: An electric motor including a labyrinth having a function for preventing foreign particles from entering an inside of the motor. A labyrinth member having a generally annular shape is fixed to a portion of a rotation shaft positioned on a front side than a front bearing with respect to an axis, by interference fit, etc., and the labyrinth member is configured to rotate integrally with the rotation shaft. The labyrinth member has at least one first opening formed on a front surface of thereof, and at least one second opening formed on an outer lateral surface thereof. The first opening and the second opening are fluidly communicated with each other within the labyrinth member.

摘要: An outer rotor motor includes an inner stator and an outer rotor. The inner stator includes a stator frame and a stator unit mounted to the stator frame. The outer rotor includes a shaft and a rotor unit fixed to the shaft. The stator frame is integrally formed from plastic as an integral structure and comprises a base and a hub extending from the base, the hub forms a chamber therein, supporting components are installed in the chamber, and the shaft extends into the chamber and supported by the supporting components such that the shaft is rotatable relative to the stator frame. In the present invention, the stator frame has an integral structure made of plastic which simplifies the structure of the motor and reduces the cost of the motor. The present invention further provides a vacuum cleaner that employs the motor.

摘要: An electric motor includes a case, a stator that includes end-windings, a rotor coupled to the case via at least one rotor bearing, at least one drive motor fluid pump, and drive motor electronics. The rotor includes a hollow cylindrical body, a first shaft portion, and a second shaft portion, a fluid feed tube having a fluid receive end and a fluid feed end, the fluid feed end extending into the hollow cylindrical body, and a plurality of fluid exit ports. The drive motor electronics power the stator with or without causing rotation of the rotor. The drive motor fluid pump pumps fluid into the hollow cylindrical body via the fluid feed tube, pumps the fluid out of the plurality of fluid ports, and onto the stator end-windings to collect heat from the rotor and the stator. The heated fluid may be used for heating a battery.

摘要: An electric motor includes a permanent magnet rotor unit and a stator unit. The permanent magnet rotor unit includes a spindle, at least one magnet fixedly disposed beside the spindle, at least one magnetic yoke fixedly disposed at an outer end of the magnet. The stator unit includes a cylindrical extension body. At least one coil is provided on the extension body. The extension body with the coil is mounted to the space between the magnet and the magnetic yoke. The electric motor doesn't use silicon steel plate, so it is light in weight. When the electric current is outputted, it doesn't need rectification. The magnetic field lines won't be diffused and interfere with each other to enhance the magnetic flux effectively.
