N compact three-phase asynchronous motors: Series 1LA8, 1PQ8, 1LL8

The three-phase motor series N compact covers outputs up to 1250 kW (at 50 Hz) in the non-standard range. A number of technical features provide this motor series with its ruggedness and long service life and ensure the highest level of availability.

N compact motors are also characterised by their high output for small frame size. The consequence of this is an extremely com­pact design that can be used to save space in a number of in­dustrial applications.

N compact motors are not only optimised in terms of their con­struction, but also in terms of their efficiency, so they also con­tribute towards lower energy consumption.

Apart from mains-fed operation, the motors of the series N com­pact are also specially designed for converter-fed operation. In combination with frequency converters from the SINAMICS and SIMOVERT MASTERDRIVES product series, they build up per­fectly interacting drive systems for variable-speed drive applica­tions.

Versions in the N compact series

Series 1LA8

The motors are asynchronous squirrel-cage motors with com­pact dimensions in fin-cooled design. They are designed for direct connection to the three-phase supply and for converter-fed operation.

  • 1LA8 for mains-fed operation
    • Designed for operation on the three-phase supply
    • Degree of protection: IP55
    • Cooling method: IC411, self-ventilated
    • Housing: Cast iron
  • 1LA8 for converter-fed operation
    • Converter-fed operation, optimised for the SINAMICS and SIMOVERT MASTERDRIVES drive systems
    • Degree of protection: IP55
    • Cooling method: IC411, self-ventilated
    • Housing: Cast iron
    • With standard insulation for voltages 500 V or with special insulation for 690 V

Series 1PQ8

The motors are asynchronous squirrel-cage motors with com­pact dimensions in fin-cooled design withforced ventilation. As these motors are forced-ventilated, no derating or only relatively minor derating (depending on their speed range) is required for operation at constant load torque and with wide speed ranges. The motors are designed for converter-fed operation with the SINAMICS and SIMOVERT MASTERDRIVES drive system.

    • Converter-fed operation
    • Degree of protection: IP55
    • Cooling method: IC416, forced-ventilated
    • Housing: Cast iron
    • With standard insulation for voltages 500 V or with special insulation for 690 V

Series 1LL8

The motors of series 1LL8 are asynchronous squirrel-cage mo­tors with compact dimensions in an open fin-cooled design with self-ventilation. They are similar in construction to 1LA8 motors. IP23 degree of protection is achieved by opening the internal cooling circuit and supplying it with external cooling air. This can increase the performance by up to 25 % as compared to the 1LA8. They are designed for direct connection to the three-phase supply and for converter-fed operation.

Motors of the 1LL8 type series are intended for installation in­doors. They must not be subjected to humid, salty or corrosive atmospheres

  • 1LL8for mains-fed operation
    • Mains-fed operation
    • Degree of protection: IP23
    • Cooling method: IC01, self-ventilated
    • Housing: Cast iron
  • 1LL8for converter-fed operation
    • Mains-fed operation
    • Degree of protection: IP23
    • Cooling method: IC01, self-ventilated
    • Housing: Cast iron

Versions with special insulation for >500V and operation without an output filter on the frequency converter are only possible on request.
