Product Description:

The MAC071C-0-JS-4-C/095-A-2/DI522LV/S004 is a brushless AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts ±10 V command signals into precise torque and speed for automated packaging lines, gantry axes, and tooling spindles that use analog control hardware. This operating style supports closed-loop motion on machines built around analog amplifier technology rather than newer digital networks. Its brushless design also supports electronically controlled commutation at the motor. By pairing with legacy amplifiers, the unit can improve motion performance without changing the core control architecture.

The motor carries winding code JS, which corresponds to the electrical values used by the matching drive. A nominal speed of 2000 rpm balances dynamic response with continuous duty in medium-inertia loads. Its heavy-duty spring-applied brake provides 6.5 Nm of static holding torque to secure vertical or suspended axes during power loss. Accurate mechanical alignment is aided by the 95 mm centering diameter that matches standard IEC flanges. Heat is dissipated through natural convection, eliminating fans and permitting sealed cabinet installation in dusty environments. This combination supports applications that must hold position at standstill while operating without external fan hardware.

Frame size 071 sets the motor's cross-sectional envelope in the MAC series. Length code C gives it the longer housing used for this frame. The tachogenerator outputs 3 V/1000 rpm for analog speed feedback during closed-loop operation, and position data come from an incremental encoder with shock-damped mounting. The combination of speed and position feedback supports stable axis control during changing load conditions. Power and brake conductors exit through a connector on side A, which simplifies cable routing on right-hand machine layouts.
