MDD041A-N-100-N2K-050GB1
The MDD041A-N-100-N2K-050GB1 is a compact synchronous motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Intended for use with digital drive controllers, the unit converts electrical energy into controlled mechanical rotation for positioning or speed-regulated tasks in automated cells. A standard housing and standard dynamic balancing keep mechanical vibration predictable during operation. It is well suited to compact axes such as small handling units, feed mechanisms, and other machines that depend on repeatable rotary motion.
Its constant torque output is rated at 0.64 Nm when the rotor is locked, providing a reference for drive sizing at standstill. During motion, the shaft can reach a nominal speed of 10000 rpm, which supports rapid indexing and high-speed positioning cycles. Mounting is centered on a 50 mm centering shoulder, and the active section corresponds to frame code 041. Service wiring enters from the rear because the combined power and feedback connector is positioned on Side B, which helps keep cabling away from the drive end. A plain shaft with a standard front-side shaft end allows direct coupling to pulleys or gearheads, and this layout can simplify routing in machine sections with limited side clearance.
To secure loads when power is removed, the integrated blocking brake applies up to 1.2 Nm of holding torque. The brake is intended to hold the axis at rest rather than serve as a dynamic stopping device during normal motion. The envelope depth follows length code A, so the motor uses the shortest body length in this frame. A radial lip shaft seal helps protect the internal bearings from dust or coolant splash. Position data is supplied by an integrated absolute encoder, allowing the drive to maintain closed-loop commutation and stable motion control.
