Product Description

The MDD090A-N-020-N2L-110PB0 is a digital AC servo motor in the MDD series by Bosch Rexroth. It is used in conjunction with intelligent digital drive controllers from Bosch Rexroth to create cost-effective and rapid response automation systems. It is a permanent magnet-excited synchronous motor with electronic commutation. The electronic commutation gives it a high cyclic load capacity, permitting its use in continuous start-stop operations with high repetition rates.

With the MDD090A-N-020-N2L-110PB0, high contouring accuracies at high feed rates are guaranteed, especially when used for cutting in high-speed ranges. It is particularly suited for high-precision operations where an extreme degree of synchronism is required, like grinding machines. This motor has two important electrical connections - one for the power connection and the encoder connection. The integrated encoder system in this MDD motor is digital servo feedback, which allows the relative indirect evaluation of the motor's position. Its temperature monitoring is via the temperature sensor built into its windings to prevent overload.

The MDD090A-N-020-N2L-110PB0 has a high degree of operating reliability due to its constructional features. It has a brushless design and lifetime-lubricated bearings for a maintenance-free operation. It can be used under adverse environmental conditions with a low risk of damage because the motor’s housing is completely sealed. Also, the connections for the motor power cable and the feedback cable are constructed according to protection category IP 65. The housing varnish is a black prime coating resistant to weathering, yellowing, chalky build-ups, and diluted acids and lyes. It should be operated at a maximum ambient temperature of 40°C and maximum relative humidity of 95%. It should be set up at a maximum height of 1000m above mean sea level.
