A machine includes a motor that includes a stator carrying a concentrated winding wound on teeth and a rotor rotatable about the stator. The rotor includes a tubular casing and permanent magnets, and a pulley coupled to the rotor.

Machine having pulley coupled to rotor and partially overlying stator, elevator system including machine, and drive method

The present invention relates to an electrical machine, comprising:

Electrical machine, in particular for an elevator

The invention relates to a rotary electric machine including a stator, powered by a polyphase current, having a magnetic circuit with teeth forming intervening slots for receiving electrical conductors. The magnetic circuit is made up of an assembly of sectors defining air-gaps intersecting the teeth at half-width.

Rotary electric machine having a stator made up of sectors assembled together

A rotary electric machine including a flux-concentrating rotor with permanent magnets disposed between pole pieces, and a stator with teeth having a free end deprived of pole swellings and a concentrated winding. The pole pieces and the magnets are configured so as to minimize the difference L&#x2212;Lwhere Lis inductance on a forward axis and Lis inductance on a quadrature axis.

Rotary electric machine having a flux-concentrating rotor and a stator with windings on teeth

An electric machine includes a stator and a permanent magnet flux-concentrating rotor. The permanent magnet flux-concentrating rotor has permanent magnets and pole pieces. The permanent magnets are engaged between the pole pieces. The electric machine also has at least one magnetic-field detector that is mounted on the stator. The at least one-magnetic-field detector is mounted on the stator in such a manner as to detect a magnetic field of the permanent magnets in a location that overlaps a peripheral region of the rotor when the machine if observed on the axis of rotation of the rotor.

Electric machine having at least one magnetic field detector

The present invention relates to a drive element such as a driving wheel for a goods-handling cart or the like, or such as a hoisting winch, the drive element comprising a wheel or a drum and an electric motor for rotating the wheel or the drum. The electric motor is a synchronous motor having a permanent-magnet rotor and a stator comprising teeth and respective individual windings on said teeth.
