Product Description

The design of highly efficient factory automation products is a globally-recognized quality of the Bosch Rexroth brand. The MDD series of AC servo motors is a family of maintenance-free motors by this brand with several product advantages and vast applications. They display high operational reliability with high overload capability and synchronous operation features. They are used in robotics, handling equipment, and transfer facilities.

The MDD071C-N-060-N2S-095GB2 is a synchronous servo motor in Bosch Rexroth’s MDD series of permanent magnet motors. This model has a frame size of 071 and a frame length of C. It is a motor of balance class R according to DIN VDE 0530, which is suitable for demanding applications as seen in grinding machines and in main spindle applications. Its motor feedback system is digital servo feedback, and it uses the optical measurement system for the relative detection of the motor’s speed and position. This position is saved in the digital drive and eliminates the need for a separate incremental encoder. Its system accuracy is ±0.5 angular minutes.

The centering diameter of the MDD071C-N-060-N2S-095GB2 is 95mm, and its output shaft is the plain type. It ensures that torque is transmitted non-positive and with no backlash. The theoretical maximum torque of the motor is 20.6Nm, while the moment of inertia of its rotor is 11.9 x 10^-4 kgm². Its power connection is to side B, and it is equipped with a blocking brake of 6.5Nm torque. This blocking brake works with electrically-actuated release and ensures the backlash-free holding of the servo axes when the machine is off. It is activated by the motor’s intelligent digital drive controller, which also maintains its switching sequences.
