Product Description:
The MAC093B-0-GS-4C-11-0-B-0-WI520-S01 is an AC servo motor by Bosch Rexroth Indramat. This motor is for industrial automation applications that require precise control and high performance. A key spec is the rated power of 4.0 kW. This is the power the motor can deliver continuously, so good for medium to high performance industrial use. The nominal speed of 3,000 min⁻¹ is the speed the motor runs most efficiently. This high speed means precise control and fast response times, which is important in many applications. The input voltage is 220-240 VAC and the output frequency range is 0.1 to 400 Hz. The control type is open-loop vector control.
The continuous torque at standstill is 14.5 (18.3) Nm. This is the torque the motor can produce when not running. The higher value (18.3 Nm) is peak torque. This is important for applications that need high startup torque or to hold a load stationary. Related is the continuous current at standstill of 27 (34) A again, the higher value is peak current. This is the current draw under the same conditions. The rotor moment of inertia is 29 × 10⁻⁴ kgm². This is important to know how fast the motor can accelerate or decelerate. Lower rotor inertia means faster response times. The motor has natural convection cooling, so it cools through the surrounding air without forced air or liquid cooling. This makes installation easier and maintenance less. The overload capacity of 150% for 60 seconds means the motor can handle temporary load surges without stalling or damage. This is important for applications with varying loads.
The motor’s electrical specs are also important. The torque constant at 20°C is 0.554 Nm/A. This is the torque produced per current flowing through the motor windings. The windings resistance at 20°C is 0.227 Ohm and the windings inductance is 4.0 mH. These affect the motor’s electrical behavior and efficiency. The maximum peak of pulse current is 134 A, which is important for drive selection and protection. The thermal time constant of 50 (45) min is how long it takes for the motor’s temperature to change significantly. The smaller value (45 min) might be for a different operating condition. This is important for thermal management and overheating.
