Three‑phase asynchronous motor 1LP with mounted DC‑excited spring‑operated brake

The naturally cooled crane motors of type 1LP4 and 1LP6 form a compact drive unit when combined with the mounted spring‑set brake and are ideal for application as traversing motors. The DC‑operated brake is designed as a holding brake, but is also capable of emergency shutdown braking operations at maximum motor speed. In the case of power failure, the brake is applied automatically by its spring force and brings the drive to a standstill.

Product range

The product range includes shaft heights 132 S to 280 M in the 5.5 kW to 132 kW power range for 4‑pole motors, or in the 3 kW to 90 kW power range for 6‑pole motors, for duty type S3‑25 % in each case. As the table below shows, more than one type of brake can be fitted to a motor; this flexibility allows the user to tailor the drive unit – comprising the motor and brake – to the exact requirements of the crane manufacturer.

The motors can also be ordered without a brake. The same article numbers apply, but the article number supplements for the brake are excluded.
