Product Description:

The MAC112A-0-VD-4-C/130-A-1/WI524LV/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. The size 112, length A housing gives a medium frame that fits into presses, handling modules, or packaging axes. Specified as a motor for analogue drives, it converts commanded current into controlled mechanical rotation inside automated machinery.

It carries an enclosure rated IP65 so the internal windings stay sealed against dust and low-pressure water jets during plant wash-downs. Under rated conditions the motor delivers 2000 min⁻¹ of shaft speed while maintaining 10.5 Nm of standstill torque for static load holding before motion begins. Dynamic events draw a peak pulse current of 71 A, enabling rapid acceleration without exceeding thermal limits set by the copper and iron geometry. Each ampere of phase current yields 0.630 Nm/A of torque, a constant that simplifies drive tuning because commanded current translates directly into predictable force. The rotor is centered by a 130 mm pilot diameter, and the DIN 6885 keyway transmits torque to the coupled load.

A factory-mounted blocking brake supplies 45 Nm of holding capacity when the drive is disabled, complementing the 14 Nm passive holding torque generated magnetically at rest. The stator’s electrical behavior is characterized by a winding inductance of 6.0 mH and a cold resistance of 0.650 Ohm, figures that dictate current rise time and copper losses. Heat generated during duty cycles disperses through natural convection and a thermal time constant of 100 min, allowing operation up to the 1000 m installation altitude without forced cooling. Position data flow through an incremental encoder with standard mounting; a standard-quality tacho generator outputs 3 V per 1000 rpm for analog speed loops. A side-A power connector streamlines installation, and the 18.5 A standstill current is managed by drives wound to the VD code impedance profile.
