The R911299946 (MSK070D-0450-NN-M1-UP1-NNNN) is an IndraDyn S synchronous servomotor from Bosch Rexroth, designed for applications requiring precise motion control. It has a motor size of 070, length D, and weighs 15.6 kg. Cooling is achieved via natural convection. The shaft includes a keyway per DIN 6885-1 and a shaft sealing ring. The 0450 winding code supports a continuous torque of 20.0 Nm at 22.0 A (standstill, 100 K), with a maximum torque of 52.5 Nm and a maximum current of 49.8 A. The motor operates up to 6000 RPM and employs an optical multiturn-absolute Hiperface encoder (128 periods), with a rotatable 240° connector. Protection class is IP65 and thermal class is 155. The holding brake provides 23 Nm of torque and is electrically released. Winding inductivity is specified at 3,000 mH.

Frequently Asked Questions

How does the electrically released holding brake improve safety in vertical axis systems?

The brake secures the load when the drive is de-energized. The mechanism prevents unwanted motion during power loss.

Why is a shaft with keyway advantageous in coupling applications?

The keyway transfers torque securely to driven parts. It prevents slippage under repeated load cycles.

What benefit does the Hiperface multiturn encoder provide here?

The encoder stores position data across power cycles. This ensures accurate recovery without homing moves.

How does natural convection cooling extend motor life in this variant?

The passive design eliminates fan failures. The setup also reduces noise and system complexity.

When is the 23 Nm brake torque most valuable?

The brake torque supports heavy loads during idle states. This is critical in packaging and lifting equipment.
