R911253072 (MDD065A-N-040-N2M-095GB0)

Description

The R911253072 (MDD065A-N-040-N2M-095GB0) is a compact and highly functional digital AC servo motor from Bosch Rexroth's MDD series. Operating at a nominal speed of 4,000 RPM, this motor achieves a maximum torque of 2.3Nm. Its design incorporates natural convection and surface cooling, allowing for heat dissipation and an enhanced overload capability. The housing, coated in weather and acid-resistant black prime, conforms to the DIN VDE 0530 Balance Class R making it suitable for demanding applications like grinding machines. The high power density of the motor makes it ideal for dynamic uses, such as in tool-changing devices and roller feeds. Its rotor, featuring low inertia permanent magnets, ensures a beneficial torque-to-inertia ratio. The motor also features digital servo feedback with an integrated multiturn absolute encoder for detecting and storing absolute indirect positions, leading to rapid startup times.
