DRL.. series asynchronous servomotors

DRL../DR2L.. series asynchronous servomotors are the link between the classical AC asynchronous motors for supply system/inverter operation and the highly dynamic synchronous servomotors with permanent magnets, both motor types with and without encoder feedback.

High rated torques and suitable for high loads

DRL../DR2L.. asynchronous servomotors are particularly suitable when high external mass moments of inertia in relation to the motor shaft have to be controlled in a reliable manner. The design and dimensioning are of such a high quality that dynamic overload values of currently up to 350% 350 % of the nominal torque can be reached for a short time. The overload capacity is divided into two dynamics packages.

The DRL../DR2L.. series also has the required torque. With its four speed classes and a high-resolution sine/cosine encoder, a high speed quality is achieved – even at low speeds.

Our asynchronous servomotor also allows you to benefit from many additional features of the modular motor system of the DR.. series.

Only half the solution without a gear unit? Then use our modular concept and combine the DRL../DR2L.. series asynchronous servomotors with a gear unit to obtain the asynchronous servo gearmotor of your choice. Or simply choose the separate servo gear unit that meets your requirements.

Your benefits

  • High overload capacity

    as a load of up to 3,5 times the nominal motor torque in relation to the motor shaft can be achieved.
  • Safe control

    Due to higher inherent mass inertia than with classic permanent magnet excited servo motors.
  • High speed quality

    in one asynchronous servo gearmotor by means of a compact unit comprising gear unit and robust asynchronous servomotor.
  • High accuracy

    by reducing the circumferential backlash in conjunction with high efficiency and high-endurance gearing.

Features

  • Torques from 5 Nm to 200 Nm
  • High rated torques for high dynamic loads
  • Load of up to 3 to 4 times the nominal motor torque
  • Safe and exact positioning in conjunction with MOVIAXIS® multi-axis servo inverter or MOVIDRIVE® application inverter
