Product Description:

The Bosch Rexroth Indramat MAC093B-0-GS-2-C/110-A-2 belongs to the MAC AC Servo Motors series and is supplied as a motor for analog drives in industrial automation. It converts amplified armature current into controlled torque for machine axes such as pick-and-place units, indexing tables, and lightweight gantries. The 093 frame size, length code B, and integrated blocking brake provide a compact motor package for applications that need secure holding at standstill. It works with current-controlled amplifiers through its built-in tacho circuit and standardized power connection, allowing straightforward integration with existing motion hardware.

Mechanical holding capability is provided by a heavy-duty blocking brake. The brake applies up to 14 Nm when power is removed, so vertical or suspended loads can remain in position during stops. A centering shoulder of 110 mm helps align the motor to gearboxes or machine frames and supports accurate mounting. Thermal regulation relies on natural convection, so heat leaves through the housing without forced airflow. Under continuous excitation, the rotor can reach a nominal speed of 4000 rpm, which suits fast cycling motion in compact automation axes. This operating range works well with analog current controllers that regulate speed from proportional feedback signals.

Speed is measured by internal tacho feedback that generates 1.5 V/1000 rpm. This proportional voltage supports stable closed-loop speed regulation in analog servo amplifiers and gives the controller a direct signal that tracks shaft rotation. The main supply conductors enter through a connector on side A, which can simplify wiring when the motor is mounted with the load side forward. Winding designation GS identifies the coil set used for moderate current density and quick dynamic response. The standard tacho arrangement supports general-purpose positioning where reliable speed information is needed without a separate feedback device.
