Product Description:
The MDD021B-N-100-N2G-032MA0 is a member of the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. Designed as a motor for digital drive controllers, it provides compact servo power for applications that require rapid positioning and velocity regulation in automated machinery. Its 021 frame size and B-length housing fit into tight mechanical assemblies, and the standard housing design maintains predictable thermal behavior during continuous duty. In automated assembly stations, the motor converts electrical command signals into controlled rotary motion for tooling, feeders, or auxiliary axes.
Mechanical interface details govern installation accuracy. A centering shoulder with a diameter of 32 mm defines the locating fit, and power and feedback conductors exit toward the front because the connections are on Side A. The harness is attached through a single Connector, reducing wiring time during service. Dynamic capability is set by a continuous stand-still torque of 0.30 Nm, allowing the servo loop to hold light loads without overheating. High-speed processes are supported by a nominal speed of 10000 min⁻¹, so rapid cycles can be achieved without mechanical gear reduction. Standard balancing minimizes additional vibration at this elevated speed.
Several design choices simplify integration with ancillary components. The motor is shipped without a blocking brake, so holding force must be generated by the drive or an external brake if the load can back-drive. Position feedback is provided through resolver feedback, giving analog angle information that is immune to electrical noise and suitable for harsh environments. The keyed shaft follows a keyway profile for positive torque transmission, and the output end is supplied without a shaft seal, which reduces friction but requires the mounting enclosure to prevent fluid ingress. Together these features tailor the unit for clean, high-speed assembly cells where minimal inertial load and quick changeover are priorities.
