Product Description:

The MAC093B-0-GS-2-C/110-B-0 servo motor manufactured by Bosch Rexroth Indramat is part of the MAC AC Servo Motors series. It is a motor for analog drives intended to supply continuous rotational motion and precise speed feedback inside automated machinery such as packaging stations and machine tools. Through its integrated tachogenerator, the unit reports real-time speed data to the drive controller, allowing closed-loop regulation without a separate digital encoder. This arrangement supports stable velocity control in systems that use analog feedback rather than serial position communication.

The motor features a centering diameter of 110 mm, giving a fixed reference surface for concentric mounting inside gearboxes or couplings. Heat is removed only through natural convection, so additional fans or coolant circuits are unnecessary when the installation provides adequate airflow around the housing. For velocity feedback, the shaft carries a tacho generator, and the feedback arrangement is tacho feedback, meaning an analog voltage proportional to speed is delivered directly to the controller. Under rated operating conditions, the rotor reaches 4000 rpm, which suits many mid-inertia axes that require high cycling speed with consistent regulation.

With a frame size of 093 and an axial length of B, the motor occupies a compact envelope that can ease retrofits in tight machine spaces. The internal copper layout follows winding code GS, which sets the resistance, inductance, and current demand used by compatible analog amplifiers. Electrical power is delivered through a connector on side B, which helps route cables along the machine without forcing a sharp bend near the housing. When spinning, the tachogenerator outputs 1.5 V per 1000 rpm, providing a linear speed signal for the controller. The motor has no blocking brake, so the load must be held by drive torque or by an external mechanical device during power-off periods.
