SIMOTICS N-compact: Series 1LA8, 1PQ8, 1LL8

The three-phase motor series SIMOTICS 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, for example, motor protection with PTC thermistors with 6 embedded temperature sensors for alarm and tripping is standard.

SIMOTICS N-compact motors are also characterized 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.

SIMOTICS N-compact motors are not only optimized 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 SIMOTICS N-compact motors are also specially designed for converter-fed operation, for example, insulated bearings are used at the non-drive-end NDE for converter-fed operation as standard to prevent damage being caused as a result of bearing currents. 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 SIMOTICS 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 converterfed operation.

1LA8 for mains-fed operation	1LA8 for converter-fed operation
Designed for operation on the three-phase supply Degree of protection: IP55 Cooling method: IC 411, self-ventilated • Housing: Cast iron	Converter-fed operation, optimized for the SINAMICS and SIMOVERT MASTERDRIVES drive systems Degree of protection: IP55 Cooling method: IC 411, 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 with forced 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.

1PQ8 for converter-fed operation
Converter-fed operation Degree of protection: IP55 Cooling method: IC 416, forced ventilation 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-cooling. They are similar in construction to 1LA8 motors. IP23 degree of protection is achieved by opening the internal cooling circuit which enables it to be supplied 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.

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

Standardline

4-pole 1LA8 motors up to 500 kW are available with a reduced range of options as the Standardline.

Benefits to the customer:

Much shorter delivery time
Can be configured with a variety of options, retaining a high degree of flexibility.

Applications

Standardline low-voltage motors are optimized for applications in pump, fan and compressor drives. The low-voltage motors are specially constructed for use in complete, coordinated drive systems comprising the motor and a SINAMICS G150 frequency converter.

Standardline motors can be ordered using order code B20.

Scope of the Standardline

4-pole version
Power range 250 to 500 kW
Types 1LA8315, 1LA8317, 1LA8353, 1LA8355 and 1LA8357
Type of construction code 0 (IM B3)
For mains-fed operation: Voltage code 6 (400 VΔ/690 VY) or 5 (500 VΔ)
For converter-fed operation: Voltage code 4 (400 VΔ), 8 (400 VΔ/690 VY) or 5 (500 VΔ)
Can be ordered for converter-fed operation, but not in the 690 V version
Possible order codes: A23, A61, A72, G50, H70, H73, K09, K10, K45, K46, K57, K83, K84, K85, L00, L97, M58 (frame size 315 only), M88 and Y53
