Product Description:

The MSK071D-0450-FN-S1-UP2-NNNN is a synchronous servomotor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It combines a size-071 frame with a D-length stator, giving a compact package for mid-range continuous torque. Used as the primary mover on coordinated axes, the motor converts drive current into precise rotary motion for packaging cells, gantry systems, and multi-axis transfer stations. Its compact housing helps it fit machines where installation space is limited, while still supporting accurate speed and position control during repeated motion cycles. That makes it suitable for axes that must accelerate, stop, and reposition with repeatable response over long production runs.

The 0450 winding works with the matching drive to establish the motor’s current-to-torque relationship, and the FN designation indicates liquid cooling for stable temperature control during demanding duty cycles. A 240° rotatable encoder connector simplifies cable routing in tight spaces, while the feedback channel uses the Hiperface protocol to transmit position data to the controller. Inside the optical system, the encoder provides 128 signal periods per revolution in a single-turn format, which gives the drive precise angular information within one shaft rotation. This arrangement supports accurate commutation and position monitoring during dynamic moves. Motion at standstill is supported by an electrically released holding brake rated at 30 Nm, and the housing has an IP65 rating to help resist dust and low-pressure water.

The motor is intended for ambient temperatures from 0 to 40 °C, which suits many cabinet-adjacent and machine-mounted installations. Its insulation system meets thermal class 155, allowing continuous copper temperatures up to 155 °C without reducing insulation life under normal operation. Mechanical power is transmitted through a shaft with keyway, which supports positive engagement with couplings, pulleys, and other driven elements. This shaft style is commonly used where a secure mechanical connection is needed to limit slip under changing loads. It can be coupled to transmission components that require a fixed rotational connection and predictable torque transfer.
