Three‑phase asynchronous motor 1LP with fitted DC‑excited spring‑operated brake
The naturally cooled crane motors of type 1LP4 and 1LP6 form a compact drive unit when combined with the fitted spring‑operated 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.
The product range includes shaft heights 132 S to 280 M in the 5.5 to 132 kW power range for 4‑pole motors, or in the 3 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.

Operating voltage
The crane brake motors are available for the following rated voltages:
The specifications change as follows for motors operating at a rated frequency of 60 Hz:
The standard model of brake coil is supplied for connection to 207 V DC (see technical data for brakes).
Motor protection
The following protective equipment can be installed (see "Article number supplements and special versions"):
Standstill heating
The motors can be fitted with a standstill heater. The heat outputs are as follows:
Motor shaft height | Heat output |
| W |
132 ... 160 | 100 |
180 ... 200 | 55 |
225 ... 250 | 92 |
280 | 109 |
For voltages, see "Article number supplements and special versions".
It is also possible to connect a voltage (which should equal approximately 4 to 10 % of the rated motor voltage) to stator terminals U1 and V1. 20 to 30 % of the rated motor current is normally sufficient to provide adequate heating.
Insulation
The motor windings are designed to comply with insulation class F.
Electric strength
See Catalog D 81.1.
1LP4/1LP6 motors are naturally cooled units without fans. Depending on the shaft height, brakes with different torques can be built onto the motors. Housing and terminal box are made of gray cast iron. The brake itself does not have a separate terminal box; all the brake connections, whether coil, microswitch or heater, are taken to the motor terminal box.
Types of construction
The motors are available in types of construction IM B3, IM B35, IM V5, IM B5 and IM V1. Other types of construction are available on request.
The position of the condensate drain holes is determined by the type of construction.
Housing
The housing and terminal box of the motor are made of gray cast iron. The DE flange and the feet (bolted‑on) can be supplied in GGG 40 as an option.
Degree of protection
The degree of protection of the standard motor models is IP55. IP56 is also available as an option. The water drain holes on motors with this degree of protection must be opened at regular intervals as part of the maintenance cycle to allow any condensate that has collected inside the motor to drain off.
Paint finish
The motors are coated as standard in a special finish RAL 7030 with a coat thickness of 180 μm. Other colors are available at additional cost. A further option is an offshore finish with a coat thickness of 220 μm.
Mounted equipment
Sensing equipment such as the POG 10 incremental encoder (made by Baumer Hübner) can be mounted on the motors. The brakes themselves can be supplied with an emergency manual release mechanism (see spring‑operated brake for SIMOTICS SD 1LG4/1LG6, special version "Emergency release with hand lever").
Terminal box
On standard models, the terminal box is mounted on the top at the DE and is always the next size larger than on the basic models of the 1LG motor. The feet are cast on.
The terminal box can also be positioned on the left or right (as viewed from the DE), but this option is only possible on motors with bolted‑on feet. If the motor is to have bolted‑on feet and a terminal box positioned on top, options K11 and J22 must be selected in the order.
On motors with a brake, the terminal box is fitted at the NDE. The option M64 must be specified additionally.
All connecting terminals for the motor and brake including auxiliaries are housed in the motor terminal box.
