Product Description:

The MSK050C-0300-NN-S1-UG0-NNNN servomotor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it delivers closed-loop rotary motion for positioning tables, pick-and-place arms, or tool drives in automated machinery. Integrated electronic feedback lets the drive regulate torque and velocity precisely, while the compact 050 frame size permits installation in confined mechanical assemblies used in packaging, printing, and handling equipment.

Heat generated in operation is dissipated through natural convection, so no auxiliary fan or liquid circuit is needed, provided that ambient airflow is available. The motor housing carries a field-installable feedback plug with a 240° rotation range, allowing the cable exit to be oriented to suit panel layouts or moving axes. Position data travels over the Hiperface protocol, combining analog commutation tracks with a digital channel so that one shielded hybrid cable can carry both power and feedback. Inside the encoder, an optical scanner produces 128 signal periods, which the drive can interpolate for fine angular resolution and smooth velocity control during slow moves.

Because the encoder is single-turn, it reports absolute position only within one revolution, so external homing is necessary if the axis rotates more than 360°. The unit is supplied without a holding brake, so mechanical stops or a counterbalance are needed when the shaft must remain fixed after power loss. A compact active section identified as motor length C balances continuous torque with overall body depth, while winding code 0300 matches power modules that can supply the required current and voltage. The plain shaft supports direct coupling to gear stages or clamping hubs without adding a keyed connection.
