The heat sink is positioned on an endshield (114) of the electric motor and/or external to a housing of the motor controller.

The fan wheel, which is driven via an electromagnetic slip coupling (6, 10) in accordance with motor speed, is mounted on the motor casing or mount (5) such that it is able to rotate freely.

Brake blocks (3) (preferably two) are mounted inside the driving wheel (1) or end plate of the electrical drive motor.

The brake blocks (3) are kept in their operating position by an electromagnet (4, 5), whose magnetic closure (5) is formed by elements of the hoist drive end plate.

Said assembly element positively engages with the end shield (25) of the motor (12) and with the housing (16), in order to harness the torque.

The membrane (24) is disposed in the end cover (3) of the electric motor (1).

The heat sink is positioned on an endshield (114) of the electric motor and/or external to a housing of the motor controller.

The fan wheel, which is driven via an electromagnetic slip coupling (6, 10) in accordance with motor speed, is mounted on the motor casing or mount (5) such that it is able to rotate freely.

The bearing end shield (10) of the electric motor (1) is sealed with the elastic diaphragm (11).

By disconnecting the brush carrier from an endbell and viewing the commutator surfaces through an endbell aperture, the commutator surfaces of the motor are inspected.

The motor incorporates at least one end shield of this construction.

The motor end cap (7) is fixed to the planetary reducer (5).

The stator is coaxially attached to a first flange that transmits the torsional force of the motor with flexible elements to a second flange positioned on the shaft.

The thin construction of the flange enables advantageous positioning of the adaptive flange.

Crankcase (4), gear housing (3) and flange (2) for mounting the motor (6) in the unit are cast in one piece.
