Patent ID: 8618704

Claim:
An electric motor having a stator which has at least one pole pair with at least two poles, and wherein each pole has a pole shoe directed inwardly towards a rotor having a circumference, said shoe further being surrounded by a winding comprising: a braking element movably mounted on the stator and which is moved towards the circumference of the rotor for braking purposes, and is moved counter to the braking force by virtue of a magnetic field which is generated when the electric motor is energized, and wherein the braking device is arranged in the stator and located between the two poles and in the circumferential direction, and wherein the braking element is in the form of a one-armed brake lever which is capable of being pivoted at one of its ends about a fulcrum in the stator; and an axially extending spring is provided, and which acts on the braking element with a braking force which is exerted in the direction of the rotor, and wherein the spring comprises a bar spring.
