The R911391211 (MSK060B-0300-NN-S1-UP0-NSNN) is a synchronous servo motor engineered by Bosch Rexroth, specified for natural convection cooling with an option for partial, externally supplied pressurized media cooling. This motor operates at a maximum speed of 4900 rpm and utilizes an optical singleturn encoder with Hiperface interface, 128 signal periods, and a 240-degree rotatable connector for precise speed and position feedback. Shaft features include a 24 mm diameter with DIN 6885-1 keyway and no taper. The unit provides continuous current at standstill of 3.3 A and continuous torque of 5.5 Nm (100 K), with maximum current of 12.0 A and torque up to 15.0 Nm. The motor conforms to DIN EN 60079 and has an IP65 protection rating per IEC 60529. Its dimensions are 156.5 mm × 116 mm × 231 mm with a weight of 5.7 kg. The product falls under the IndraDyn S Synchronous Servomotor series (motor size 060, length B, winding code 0300) and offers standard and explosion protection designs.

Frequently Asked Questions

What is the motor’s continuous current requirement?

At rated operation, the motor requires 3.0 A continuous current at standstill. This current specification supports efficient power usage and safe drive compatibility.

What is the maximum effective current value?

The maximum effective current is 12.0 A during short-term operation. This allows higher torque generation but requires monitoring to prevent overheating and drive overload.

What is the rotor inertia rating specified?

Rotor inertia is 0.00048 kg·m², determining acceleration and deceleration characteristics. Lower inertia benefits fast positioning, while higher inertia stabilizes against load disturbances.

What is the motor’s rated speed capacity?

The motor operates at a nominal speed of 3,000 rpm, balancing torque and velocity. This rating ensures smooth operation across general automation and machine tools.

What is the maximum speed specification here?

The maximum permissible speed is 4,800 rpm under light load conditions. This enables flexible use in high-speed applications but requires proper bearing and coupling selection.
