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.
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 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 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.
