Product Description:

The MAC90B-0-PD-1-B/110-A-1/J625 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, it transforms current commands into controlled rotation for machine tools, packaging lines, and handling modules. That operating style suits axes that rely on an external amplifier for repeatable speed and position control during production. The motor mounts with a 110 mm pilot and keeps all electrical terminations on one face, simplifying cabinet wiring in compact automation cells. This placement keeps motor leads short and helps reduce electromagnetic interference inside busy production cells.

At standstill, the motor delivers 7.2 Nm of continuous torque while drawing 11.9 A, supporting holding duty or slow indexing. When the shaft reaches 2000 rpm, the motor maintains steady speed under rated load. For rapid moves, the windings permit a 86 A peak pulse that produces short bursts of high torque. A spring-applied brake supplies 6.5 Nm of holding torque and releases with 0.7 A, helping keep vertical axes in place when power is removed. The IP 65 housing blocks dust and water jets, and the output shaft measures 24 mm in diameter to fit standard couplings.

Thermal mass reaches equilibrium after 60 min, so brief overloads rarely push the windings beyond a safe operating temperature. Current control is simplified because the motor develops 0.67 Nm/A, which allows the analog amplifier to estimate torque directly from commanded current. Dynamic behavior is influenced by the 5.1 mH phase inductance and 0.97 Ω resistance, values used by the drive for commutation and fault handling. Power reaches the stator through a 1.5 mm² cable terminated with an INS 108/02 plug, and all connectors are placed on Side A for easy access. Grouping the electrical interface on one end of the motor helps when nearby machine members limit side clearance.
