Intended for direct coupling with digital drive controllers, the unit provides high-speed rotary motion for compact automation axes such as pick-and-place heads, indexing tables, and small conveyors in industrial environments. Its size 021 stator and B-length frame fit machine sections where installation space is limited, while synchronous operation supports accurate speed control and repeatable positioning in short-cycle equipment.\u003c\/p\u003e\u003cp\u003eIt uses standard rotor balancing to limit vibration, and both the housing and the front shaft end follow the series standard pattern. A centering diameter of \u003cstrong\u003e32 mm\u003c\/strong\u003e establishes the reference surface for mounting against flanges or gearheads. Power and feedback conductors leave the frame on \u003cstrong\u003eside B\u003c\/strong\u003e through a single circular connector, which simplifies cable routing in confined cabinets. When the rotor is locked, the stator can sustain \u003cstrong\u003e0.30 Nm\u003c\/strong\u003e of continuous torque, while the winding permits a nominal operating speed of \u003cstrong\u003e10,000 rpm\u003c\/strong\u003e for rapid duty cycles. Position information is delivered by an \u003cstrong\u003eintegrated absolute encoder\u003c\/strong\u003e, allowing the controller to recover the mechanical zero without a homing move, and the rear face carries no secondary shaft.\u003c\/p\u003e\u003cp\u003eThe motor has a \u003cstrong\u003eplain shaft\u003c\/strong\u003e, so torque transfer relies on friction couplings instead of keyed interfaces. This shaft style is commonly paired with clamp hubs that provide low-backlash transmission on small servo axes. Because the motor is supplied \u003cstrong\u003ewithout a blocking brake\u003c\/strong\u003e, any load holding during power loss must be achieved with external devices. For systems that use analog sinusoidal feedback, the electronics can supply \u003cstrong\u003eresolver feedback\u003c\/strong\u003e signals as an alternative to the absolute channel. The unit ships \u003cstrong\u003ewithout a shaft seal\u003c\/strong\u003e, so additional enclosure measures are required when fluids or fine dust are present.\u003c\/p\u003e","brand":"Bosch Rexroth Indramat","offers":[{"title":"Unstocked","offer_id":52038673072429,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/mdd021b-n-100-n2k-032fb0__097e6e84-28d2-40cb-b1ff-2f60dbd45906.webp?v=1777966599","url":"https:\/\/servosupplier.com\/products\/mdd021b-n-100-n2k-032fb0","provider":"Servo Supplier","version":"1.0","type":"link"}
