Product Description:
The MDD021A-N-100-N2K-032FA0 is a brushless AC servo unit produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed to interface directly with the company’s digital drive controllers, the motor supplies precise rotational motion for compact pick-and-place heads, small indexing tables, and similar automation axes where high speed and tight position loops are required.
At the mechanical core of this model, the rotor is balanced to the standard grade, and its centering flange measures 32 mm, a dimension that defines the locating register when the motor is clamped to a machine frame. Electrical and feedback leads exit on Side A through a single industrial Connector, simplifying panel routing. The continuous torque available at standstill is 0.15 Nm; this value indicates the maximum static load the motor can hold without exceeding permissible temperature rise. When the drive excites the three-phase windings at rated frequency, the shaft can reach a nominal speed of 10000 min⁻¹, supporting rapid cycle times in lightweight mechanisms. Compact proportions are achieved by the 021 frame size and the short “A” length code, while the housing remains the standard un-finned type for cabinet-mounted installations.
For feedback, the unit provides motor commutation signals through Resolver feedback and absolute position data via an Integrated absolute encoder; this dual system allows the controller to switch between coarse and fine resolution during startup and runtime. Motion is transferred through a Plain shaft that lacks a shaft seal, so the mounting arrangement must prevent lubricant migration into the interior. Because the design is supplied without a blocking brake, static holding torque must be delivered by the drive or an external clamp. The shaft is only present on the drive end, aligning with the specification “standard without side B shaft end,” and the product is intended exclusively for digital drive controllers that monitor thermal load through resolver wiring.
