Product Description:
Bosch Rexroth Indramat builds the MSK076C-0300-NN-M2-UP1-RNNN for the MSK IndraDyn S Synchronous Motors series. This servo motor supplies closed-loop rotary motion for positioning tables, packaging axes, and other automated machinery that require repeatable speed and torque under drive control. Its synchronous design supports coordinated motion in machines where acceleration, settling behavior, and speed stability must remain consistent from cycle to cycle. Integrated optical feedback and an electrically released brake help the motor deliver accurate command tracking while holding a load in place when power is removed.
The motor uses natural convection for cooling, so no external fan or liquid circuit is required. Feedback cabling exits through a connector that is rotatable through 240°, which lets the plug be directed toward the least obstructed cable path inside a cabinet. Position data move to the drive over the EnDat2.1 serial interface, which also supports bidirectional diagnostic communication. Within the encoder, each mechanical turn is divided into 2048 signal periods, helping the drive maintain smooth velocity control and accurate positioning. The encoder also has multiturn absolute capability, so shaft rotations remain known across power cycles and a homing pass is usually unnecessary after a restart.
An electrically released brake provides 11 Nm of holding torque so vertically oriented loads can remain in position when the drive is disabled. Output torque is transmitted through a shaft with a keyway, which matches standard keyed couplings and helps prevent slip during reversing duty. The motor has increased concentricity to reduce radial runout and support stable encoder accuracy across the 076 frame size. Winding group 0300 sets the motor’s voltage constant for medium-speed operation with compatible IndraDrive controllers, while length code C provides additional thermal mass without requiring a larger frame. The brake is intended for holding when power is removed, while normal stopping action is managed by the drive during operation.
