Asynchronous Servomotors

When it comes to asynchronous servomotors, the emphasis is on cost-effectiveness and a high output. They have a favorable price, low operating costs and can be used with or without encoder. The 1PH7 and 1PL6 motors have a revolutionary design without housing. In this case, the stator is also the motor enclosure – which makes the motor compact and light. The motor cooling, integrated in the stator, saves space and cools precisely where the heat is generated. Thanks to the expanded range of frame sizes up to size 280, our servomotors are now available up to 630 kW.

1PH7: The compact highperformer at a favorable price

If the size and technical features of standard motors are not adequate for certain industry sector applications, then our stator-cooled 1PH7 asynchronous servomotors with degree of protection IP55 can be used to provide the optimum drive solution. Up to frame size 225, the 1PH motors are equipped with rugged, permanently lubricated bearings – even for increased cantilever forces for belt and pinion drives as well as the highest speeds, as are often required for test stands.

1PL6: The BIG one for machines with the highest power density

If you prefer a compact three-phase drive over DC solutions or if the ambient conditions allow the use of open motors, then our 1PL6 motors cannot be beaten when it comes to costeffectiveness and output. 1PL6 servomotors, available in frame sizes 180 to 280, are open-circuit ventilated asynchronous motors with stator and rotor cooling. This motor cooling means that outputs are available up to 630 kW. 1PL6 motors are in full compliance with IEC 60034-5 with degree of protection IP23.

1PH4: Rugged water-cooled motors for special industry sectors

Our 1PH4 water-cooled servomotors are the optimum solution for extreme ambient conditions, such as high temperature, dust, dirt or aggressive atmosphere where air cooling cannot be used but suitable cooling water is available. These motors have water intake and discharge connections at the non-drive end instead of a fan unit which means that they can develop their full output independent of the ambient conditions.
