MAC90B-0-PD-1-B/110-A-C/J1250C/S015
MAC AC Servo Motors
The Bosch Rexroth Indramat MAC90B-0-PD-1-B/110-A-C/J1250C/S015 from the MAC AC Servo Motors series is engineered for high-performance industrial automation with a continuous torque at standstill of 7.2 Nm and a continuous current at standstill of 11.9 A. This AC servo motor operates at a nominal motor speed of 2000 min⁻¹ and can sustain short-term demands with a peak pulse current of 86 A. Rated with a protection category of IP65 and insulation class F, it maintains reliable operation in harsh environments. The motor’s mass of 18 kg and compact footprint facilitate straightforward integration into precision motion systems.
Thermal management is optimized through dual thermal time constants: a standard 60 minutes under natural cooling and an enhanced 45 minutes with improved dissipation. Under elevated thermal loads, the unit delivers up to 10.5 Nm max torque at 17.4 A max current, ensuring greater torque density during demanding cycles. Electrical dynamics are finely tuned by a torque constant of 0.67 Nm/A, winding inductance of 5.1 mH, and winding resistance of 0.97 ohms at 20 °C, promoting precise current-to-torque conversion and rapid response. The rotor’s inertia of 36 × 10⁻⁴ kgm² contributes to smooth acceleration and high positional accuracy.
Built for rugged industrial conditions, the motor operates reliably within an ambient temperature range of 0 to +45 °C and can be stored or transported between –20 to +80 °C without degradation. Its robust construction and balanced electrical-mechanical characteristics make the MAC90B-0-PD-1-B/110-A-C/J1250C/S015 an ideal choice for automated manufacturing, robotics, and high-precision indexing applications where consistent performance and longevity are paramount.
