MDD025B-N-100-N2K-040PD1
The MDD025B-N-100-N2K-040PD1 is a motor for digital drive controllers produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. With frame size 025 and length code B, this standard-housing servo motor fits compact axes where limited mass and installation space are important. Standard balancing helps reduce vibration transfer to nearby machine parts during fast motion, and the integrated absolute encoder provides position data as soon as power is applied, which supports immediate startup in automated handling units or tooling stations.
At standstill, the rotor can deliver a continuous torque of 0.60 Nm, which is the maximum static load the drive can hold without overheating the motor. During motion, the windings support a nominal mechanical speed of 10,000 rpm, allowing direct coupling to high-speed spindles or indexing tables when additional gearing is not desired. Precise concentricity is supported by the 40 mm centering diameter, and the power and feedback plugs are located on Side B at the rear of the housing to keep cable routing in one direction. Position sensing uses resolver feedback processed by the drive controller, while the encoder retains multi-turn position information when power is removed.
The motor is supplied with a connecting cable with coupling unit, so field wiring can be disconnected without opening sealed areas of the machine. A blocking brake rated at 1.0 Nm locks the shaft when the controller engages it, helping prevent unwanted movement on vertical axes and other applications that must hold position at rest. Torque is transmitted through a hardened keyway on the drive-side shaft, no shaft is provided on the opposite face, and a radial shaft seal helps protect the internal bearings from coolant spray and dust during continuous industrial operation.
