MDD025A-N-100-N2G-040FL0
The MDD025A-N-100-N2G-040FL0 is a compact synchronous motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded current into rotary motion for pick-and-place stations, light conveyors, and small tooling heads. The motor is suited to servo applications that need precise motion in a small frame without adding unnecessary bulk to the axis. Its compact format helps limit moving mass on smaller axes, which supports responsive motion in short-cycle automation tasks. The integrated feedback path also lets the controller regulate speed and position with consistent response during repeated starts, stops, and indexing moves.
This model delivers a continuous standstill torque of 0.33 Nm, allowing stable holding at zero speed or controlled low-speed feed motion without immediate thermal overload. Its rated mechanical speed reaches 10000 rpm, making it suitable for fast indexing and other high-throughput machine cycles. Position data are returned through resolver feedback, which provides rotor angle signals to the drive during operation. Mechanical centering on a 40 mm pilot helps keep the motor flange aligned with the attached load. Power and signal terminals use a connection on the left side with a keyed circular connector, which can simplify cable routing where installation space is limited.
The unit is supplied without a blocking brake, so holding force must come from drive torque or an external clamp when the axis is stopped. It uses a plain shaft, and the 025 size with motor length code A helps keep rotor inertia low for quick acceleration and short settling times. The aluminum housing is easy to mount and supports the compact layout of the motor in small machine assemblies. The motor is built without a shaft seal, which suits dry, clean installations where reduced friction is preferred. Standard dynamic balancing helps limit vibration during high-speed operation, and the bearing arrangement supports stable running in normal industrial duty.
