Product Description:

The MAC090B-O-JD-5-C/110-A-0/K1520LV is an AC servo motor built by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed for analog drive systems, it converts controlled electrical energy into precise rotary motion for positioning and velocity control in automated machinery. Continuous feedback is provided through an internal tacho generator, allowing the connected drive to close the speed loop without the need for an external encoder. This arrangement supports stable motor control in applications that require repeatable speed response and accurate rotary movement.

The motor draws a continuous stall current of 18.2 A and develops a continuous stall torque of 6.7 Nm, so loads can be held within thermal limits during low-speed or standstill operation. Under rated excitation, it reaches a nominal speed of 3000 rpm, making it suitable for conveyor, gantry, or spindle duties. Momentary demands are supported by a peak pulse current of 137 A, which helps the motor handle rapid acceleration and deceleration. Electromagnetic conversion is indicated by a torque constant of 0.41 Nm/A, meaning each ampere delivered by the analog amplifier produces a proportional amount of shaft torque. The stator windings have 2.0 mH of inductance and 0.38 Ω of resistance, values that influence current rise time, commutation behavior, and thermal loading during high-frequency drive commands.

The housing is sealed to IP65, which helps prevent dust ingress and protects against low-pressure water streams. A centering diameter of 110 mm aligns the flange with gearboxes and mounting fixtures for accurate installation. Dynamic response is influenced by a rotor inertia of 0.0036 kgm², balancing smooth motion with responsive setpoint changes. Heat accumulation follows a thermal time constant of 60 min and is dissipated to ambient air by natural convection, eliminating the need for forced cooling. The unit is supplied without a blocking brake, power leads exit on side A, and a standard tacho is used for velocity feedback.
