Product Description:

The Bosch MS2N05-D0BRN-CMSG1-NNNNV-GA Synchronous Servo Motor combines reliable torque, high resolution feedback and compact design. The motor integrates an advanced 20 bit encoder system. It ensures accurate positioning and efficient operation with stable mechanical properties.

This MS2N05-D0BRN-CMSG1-NNNNV-GA servo motor delivers a standstill torque of 9.35 Nm at 100 K conditions. The rated speed of the servo motor is 3510 revolutions per minute. It achieves a maximum torque of 34.0 Nm at + 20 °C when cold. The maximum current supported is 30.3 A. Its winding resistance at 20 °C measures 1.76 Ohm. The rated current at 100 K is 3.95 A while the standstill current is 7.2 A under the same conditions. The motor has five pole pairs which ensures smooth rotation and enhanced torque density. The thermal time constant of the winding is 45.8 seconds which indicates moderate heat dissipation characteristics. The leakage capacitance of the component is 3.29 nF that ensures safe EMI behavior in electronic environments. The integrated holding brake in the motor provides a holding torque of 10 Nm that is useful for position holding without power. The brake operates with a connection time of 30 ms and weighs 1.1 kg.

The encoder system used in the MS2N05-D0BRN-CMSG1-NNNNV-GA servo motor is multiturn with absolute feedback over 4,096 revolutions. It offers 20 bit resolution and uses the ACUROlink interface for precise feedback. This enables detailed position tracking across multiple turns. The encoder design allows efficient and accurate control in positioning applications. The electrical interface of this MS2N series servo motor is a rotatable M23 connector with a single cable design. This simplifies installation and cable routing in machine layouts. The single cable approach also reduces system complexity and maintenance.
