The R911292760 (MHD131D-024-PG0-BN) is a synchronous servo motor from the MHD series, featuring a multiturn absolute encoder for precise shaft position detection over more than 4096 revolutions. The motor operates on a 3-phase AC supply, 400V-480V, via an output connector oriented toward side B. It is equipped with liquid cooling, a surface thermal time constant of 60 minutes, and natural cooling at 140 minutes. Key parameters include a continuous standstill torque of 160 Nm, nominal speed of 2000 rpm, 173V constant torque voltage, and torque capacity of 1.99 Nm/A at 20°C. The unit is built to insulation class F (DIN VDE 0530 part 1) and rated IP65. It features 4 pole pairs, a total mass of 113 kg, and a rotor moment of inertia of 382x10⁻⁴ kg·m². The centering diameter is 250 mm, flange size 260 mm, and the overall motor size is designated 131 with motor length D. The plain shaft includes a shaft seal, and there is no holding brake. The operational ambient temperature range is 0 to +40°C.

Frequently Asked Questions

Why does MHD131D-024-PG0-BN include a 260 mm flange?

The flange matches standard mounting dimensions on machines. It provides firm attachment and stable alignment during torque transmission.

How does MHD131D-024-PG0-BN prevent internal contamination?

Its shaft seal stops dirt and coolant from entering. Clean internal components extend bearing life and maintain reliability.

Why is the 024 winding code valuable in MHD131D-024-PG0-BN?

The 024 winding lowers copper losses in each phase. Reduced resistance improves torque efficiency and motor temperature stability.

Why is MHD131D-024-PG0-BN ideal for quick reversals?

The D-length rotor balances internal mass across its axis. Balanced weight reduces vibration during fast direction changes.

How does MHD131D-024-PG0-BN encoder improve motion accuracy?

The encoder sends precise position data to the drive. It allows immediate correction for smoother and more controlled motion.
