Product Description:

The MSK101E-0450-NN-M1-BP3-NNNN belongs to the MSK IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is an IndraDyn S synchronous servomotor used for closed-loop positioning and speed control in automated machining cells, material-handling axes, and packaging equipment. The motor has frame size 101 with length E, and winding code 0450 matches it to compatible IndraDrive controllers. A standard housing with a keyed shaft supports direct coupling to gearboxes or driven loads, while its electrically released holding brake secures vertical or suspended axes when power is removed.

The motor is cooled through natural convection, so no external blower or liquid circuit is required. An electrically released brake supplies 120 Nm of static torque to lock the rotor during downtime or emergency stops. The enclosure carries an IP65 rating, which helps protect internal components from dust and water jets common in industrial environments. Power enters on the B-side of the stator housing, which can simplify cable routing when the motor is installed in compact machine spaces. Thermal insulation class 155 sets the maximum winding temperature and supports continuous duty across the stated operating ambient range of 0 to 40 °C without derating. This layout supports applications that need a sealed motor without auxiliary cooling hardware.

Feedback and commutation data are delivered through a Hiperface encoder interface. The scanning system resolves position to 128 signal periods per revolution, and the optical design resists magnetic interference from adjacent drives. Multiturn capability records up to 4,096 mechanical revolutions through a multiturn absolute counter, which allows the control system to retain position information after power cycles. This feedback supports accurate startup and stable closed-loop motion on indexing, transfer, and positioning axes.
