Product Description:

The MAC025C-0-JS-4KE/040-B-0/WI670LV/S008 is a servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It converts drive-generated current into regulated rotary motion, enabling precise positioning and velocity control on lightweight axes such as pick-and-place heads, indexing tables, and feeders used in automated machinery. Compact frame dimensions and standardized mounting interfaces allow the unit to fit existing mechanical layouts without special adapters.

The stator uses winding code JS, and this electrical pattern determines the resistance and inductance values so an analog drive can deliver rated torque across the speed range without exceeding current limits. The frame size is C, which corresponds to the outside diameter and bolt circle used by other C-frame MAC motors. The magnetic stack length is 025, which gives the motor its active iron depth and supports continuous torque for small payload applications. Cooling relies on natural convection, so heat is dissipated through the housing surface without forced-air blowers. The motor has no blocking brake, so the load must be held by external mechanics or by maintained servo torque when the shaft must stay in position during power loss.

The power leads exit through a connector on side B, placing the high-current plug opposite the shaft end to keep cabling clear of motion zones. Rotor position is measured by an incremental encoder with standard mounting, which supports common tachometer-based feedback loops. It is also equipped with tachofeedback and an incremental or absolute encoder for applications that need finer resolution or multiturn data. It is a motor for analog drives, so it interfaces directly with voltage-controlled or current-controlled amplifiers that use analog command signals rather than digital fieldbus communication.
