Product Description

Bosch Rexroth’s MDD servo motors are permanent magnet-excited with electronic commutation. Their permanent magnets are obtained from rare earth materials, giving them low inertia motors for high dynamics. They are synchronous motors that can be used to create rapid-response automation systems when combined with the Indramat digital drive controllers. These motors ensure high contouring accuracies at high feed rates, particularly when used for cutting at high-speed ranges. They have a brushless design and bearings that remain lubricated throughout their service life.

The MDD112B-N-040-N2L-130PA0 is a servo motor in the MDD series built for high-precision operations where an extreme degree of synchronism is required, like in grinding machines. Its housing design permits cooling by natural convection and surface cooling.; hence, it can be used for operations that involve extreme loads. Like others in the series, it has a compact construction which gives it a high power-to-weight ratio. Its electronic commutation feature also gives it a high cyclic load capacity that is suitable for continuous start-stop operations with high repetition rates.

There is a shaft with a keyway according to DIN 6885-1 in the MDD112B-N-040-N2L-130PA0 for form-fitting shaft hub connections. Its motor feedback option is digital servo feedback which uses the optical measurement method for high-precision operations. The system accuracy of the encoder is ±0.5 angular minutes. This motor also has high overload capabilities because heat dissipation is via natural convection and conduction from the stator windings to the outside wall of the motor housing. It should be operated at an ambient temperature between 0°C and 40°C and maximum relative humidity of 95%. The motor should also be set up at a maximum height of 1000m.
