Abstract

A motor having a shaft bearing a rotor, a pulley driven by the shaft, at least one caliper brake acting on a wall turning with the pulley, and at least one axial brake.

Claims

1. A motor comprising:

a shaft bearing a rotor,

a pulley driven by the shaft,

at least one first caliper brake acting on a wall turning with the pulley, and

at least one second axial brake, wherein the wall is one piece with the pulley.

2. The motor as claimed in claim 1, the wall being formed by a disk.

3. The motor as claimed in claim 2, the disk extending radially.

4. The motor as claimed in claim 1, the shaft bearing a rotor with permanent magnets.

5. The motor as claimed in claim 1, comprising two first caliper brakes.

6. The motor as claimed in claim 5, the two first caliper brakes being arranged symmetrically relative to a median plane containing the longitudinal axis of the motor.

7. The motor as claimed in claim 5, an angular difference between the brakes being less than or equal to 70°

.

8. The motor as claimed in claim 1, an external diameter of the wall being less than or equal to 60 cm.

9. The motor as claimed in claim 1, an external diameter of the pulley being less than or equal to 50 cm.

10. The motor as claimed in claim 1, the second axial brake serving as a service brake.

11. The motor as claimed in claim 1, a braking torque of the second axial brake being greater than that of a first caliper brake.

12. The motor as claimed in claim 1, the rotor turning between bearings.
