AC Line

Single-disc brake for AC operation

Spring-pressure single-disc brakes which can be connected directly and without rectifier to an AC supply, e.g. in the motor connection box.

About AC Line

The AC LINE includes spring pressure single-disc brakes which can be connected directly and without rectifier to an AC supply, e.g. in the motor connection box. Due to its working principle the switching times of the brake are significantly shorter than with comparable DC brakes. Electromagnetically operated spring pressure brakes build up the braking torque when the current is switched off.

Specifications & technical details

Nominal Moment1 Nm - 75 Nm
VoltageDC 230, 400 V
Protection ClassIP 44, IP 54

Operating principle

The spring-applied single-disc brake is designed to operate dry. The force generated by an electromagnetic field is utilized to overcome the braking effect produced by the spring force. The spring-applied single-disc brake engages in unpowered condition and releases when three-phase AC voltage is applied. The form-fit connection between the friction disc and hub and the connection of the hub with the machine shaft (e.g. motor shaft) ensure that the torque generated by the spring-applied brake (brake torque) is reliably transmitted to the machine (motor).
