Product Description:
The MAC041B-0-BS-4-E/050-A-1/WI671LV belongs to the MAC AC Servo Motors series and is built by Bosch Rexroth Indramat. It is a compact brushless unit intended for integration in positioning axes where accurate torque and speed control are required for pick-and-place arms, small conveyors, and table drives. By combining a permanent-magnet rotor with closed-loop feedback, the motor works with analog servo amplifiers that modulate current to generate proportional mechanical motion for industrial automation tasks. This operating principle supports smooth reversals and repeatable positioning in equipment that cycles frequently through short moves. The compact housing also suits installations where available mounting space is limited and cable routing must remain clear of adjacent machine components.
The motor releases waste heat through passive natural convection, so the installation needs sufficient clearance around the housing to maintain winding temperature. The motor has a size of 041, which keeps the housing compact for small machine axes. Its frame length of B supports low rotor inertia for rapid start-stop cycles without overshoot. Power conductors terminate through a connector on side A, which helps route cables away from moving machine members. Velocity information is produced by internal sensors that provide tacho feedback and encoder signals, allowing motion data to be returned to the drive for closed-loop control.
A standard blocking brake is fitted to clamp the shaft when the enable signal is removed, helping prevent load drift on vertical axes. The motor uses an incremental encoder with standard mounting to transmit phase-quadrature pulses directly to the amplifier. Classified as a motor for analog drives, the unit accepts conventional ±10 V velocity or current commands for compatibility with legacy MAC control platforms. This arrangement supports precise speed regulation and stable position feedback during repetitive motion cycles.
