Product Description:

The Bosch Rexroth Indramat MAC093B-0-JS-3-C/110-A-2 belongs to the MAC AC Servo Motors series and is supplied as a motor for analog drives used in position and speed control loops on presses, transfer lines, and packaging machines. The unit is built around the size 093 stator frame and length code B, giving the mechanical envelope expected in medium-inertia axes while staying compatible with Indramat MAC mounting patterns. Within an automation cell, it converts commanded current from the drive into motion and enables closed-loop actuation without mechanical gearing changes.

The blocking brake develops 14 Nm of static holding torque so vertical loads remain stationary once power is removed. A centering diameter of 110 mm locates the flange accurately on precision machine plates and helps keep runout low. Heat produced by the winding is removed through natural convection, eliminating the need for auxiliary blowers in cabinets with moderate ambient temperatures. The rotor is designed for continuous operation at 3000 rpm, a speed that matches the bandwidth of most analog velocity loops. For velocity feedback, a tacho generator provides 3 V/1000 rpm, allowing the controller to scale gain without external dividers.

The motor incorporates a heavy-duty blocking brake whose friction surfaces are sized for frequent emergency stops, extending service life compared with standard shoes. Position feedback is supplied through tacho feedback and a second shaft end, allowing simultaneous electrical and mechanical sensing for redundancy or manual jogging fixtures. The power leads exit through a connector on side A, simplifying cable routing in gantry mounts where side B faces moving structures. Electromagnetic behavior follows winding code JS, which sets the phase resistance and inductance so the analog drive can reach current reference rapidly while keeping the tacho signal within its linear range.
