Fan with brake lining

A fan brake (also known as a friction lining fan or "Ferodo") is a key component of an electric hoist's lifting system, performing two important functions simultaneously: cooling the electric motor and holding the load.

Operating Principle and Function
Brake Function: The mechanism is part of a normally-closed braking system. When the motor is de-energized (at a standstill), a powerful spring presses the friction lining (Ferodo), integrated into the fan, against the motor housing or brake disc, securely holding the shaft and preventing the load from falling or descending unintentionally.

Fan Function: The fan blades, rigidly connected to the motor shaft, rotate with it during operation. This ensures intensive cooling of the electric motor housing, which is critical to preventing overheating during intensive use.

Brake Release: When voltage is applied to the motor, an electromagnetic field is created that attracts the armature, compressing the spring and releasing the braking surface. The motor shaft can rotate freely, raising or lowering the load.
