Product Description:

The KSD076C-0350-NN-M1-1G0-NNNN is an integrated servo motor-drive unit manufactured by Bosch Rexroth Indramat for the KSD IndraDrive Mi Motors series. By combining power electronics, feedback, and a synchronous rotor in one housing, the device provides decentralized axis control for modular machines, conveyors, and pick-and-place stations. It generates the variable-frequency output required for precise positioning in automated cells while reducing the amount of separate equipment installed in a control cabinet.

During steady operation, the motor delivers 8.7 Nm of continuous torque at a 60 K winding temperature rise, while peak mechanical demand can be met with up to 29.0 Nm of maximum torque. A winding rated speed of 3500 rpm sets the base electrical frequency and supports gearbox selection for the intended motion range. Current drawn from the DC bus tops out at 17.7 A, and each ampere produces torque in proportion to the 1.85 Nm/A torque constant, giving predictable acceleration profiles. The shaft tolerates up to 40 N of axial load without exceeding bearing limits. Position feedback is supplied by an optical multi-turn encoder that resolves 128 × 2¹³ counts per revolution, supporting high-precision motion data exchange with the integrated controller.

Heat generated during drive switching is removed by natural convection, eliminating the need for fans or liquid circuits and aligning with the 25-minute thermal time constant that governs internal temperature rise during duty-cycle changes. The encoder maintains an absolute range of 4096 revolutions, allowing the PLC to recover the axis position after a power cycle without requiring a homing routine. Electromotive force increases with speed at 113.8 V/1000 rpm; this constant helps the drive limit regenerative voltage during rapid deceleration. The optical encoder supplies position data directly to the integrated controller, while the cooling method supports operation in compact machine frames with limited space for auxiliary equipment.
