Product Description:

The MDD115C-015-N2L-130PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers where precise closed-loop velocity and torque control are required on automated axes such as gantries, presses, and material-handling stations. The 115 frame size and C length code give the motor a compact form for medium continuous torque, and the wiring exits on side B to simplify cable routing in enclosed machine layouts. Its synchronous design supports repeatable motion on axes that cycle through frequent starts, stops, and load changes.

Under continuous stall conditions, the winding can conduct up to 40.2 A and produce 47.0 Nm of holding torque without overheating. When the application calls for motion, the rotor reaches a rated speed of 1500 rpm, and the motor accepts short overloads up to 180.7 A for rapid acceleration. A torque constant of 1.17 Nm/A links commanded current to produced torque, which helps the drive respond predictably during speed and position control. Position data is returned through integrated digital servo feedback, and mechanical coupling is handled by a 32 mm k6 shaft with a 10 × 8 × 45 mm keyway. Alignment to the mating flange is guided by a 130 mm j6 pilot, and the power connector on side B helps separate high-current conductors from feedback wiring.

The motor’s dynamic behavior is influenced by a rotor inertia of 222 × 10⁻⁴ kg·m², and its theoretical ceiling torque reaches 146.1 Nm for brief demand peaks. Electrical response is shaped by a phase inductance of 3.5 mH and a phase resistance of 0.21 Ω, which affect current rise and regenerative voltage during deceleration. A 90-minute thermal time constant allows extended duty cycles before winding temperature approaches its limit, which helps the motor handle processes that alternate between dwell periods and higher load segments.
