MDD025C-N-100-N2G-040PD0
Bosch Rexroth Indramat's MDD025C-N-100-N2G-040PD0 is a synchronous motor for digital drive controllers in the MDD Synchronous Motors series. The model provides rotary motion for compact axes used in electronic assembly lines, packaging units, and semiconductor tools. As a servomotor, it converts regulated current from the drive into proportional torque and speed, allowing closed-loop motion profiles to follow machine commands with high accuracy, repeatability, and stable response during continuous duty.
The motor reaches a nominal speed of 10000 rpm, allowing rapid indexing cycles while staying within the drive's frequency bandwidth. Continuous torque at standstill is rated at 0.90 Nm, so the motor can hold a locked shaft load continuously without exceeding thermal limits. A centering diameter of 40 mm fits standard mounting collars for accurate alignment between the housing and machine frame. All power, resolver, and brake conductors exit on side B of the stator end plate, which helps keep cabling directed toward the rear. Rotor position is detected through resolver feedback, which supplies analog sine-cosine signals that remain stable at high rotational speeds.
The output shaft uses a keyway, permitting positive engagement with a keyed hub for slip-free torque transmission. Motor power is delivered through a prewired connecting cable with coupling unit, which reduces installation complexity and limits the number of separate connectors in the cabinet. For applications that rely on external clamps or dynamic braking, the motor is supplied without a blocking brake, so no residual drag is introduced when drive torque is disabled. A dedicated lip around the spindle carries a shaft seal that helps limit oil leakage and block airborne contaminants. The overall motor length corresponds to length code C, which indicates the axial size used for envelope planning in multi-axis stages.
