Product Description:
The KSD071C-0240-NN-S1-1P0-NNNN is an integrated servo motor-drive unit from Bosch Rexroth Indramat’s KSD IndraDrive Mi Motors series. By combining power electronics and a servo motor within a single housing, the device provides decentralized motion control without requiring a separate cabinet-mounted inverter. It supports conveyors, packaging axes, and assembly stations that require precise position feedback and compact machine layouts.
The motor reaches a rated shaft speed of 2400 rpm, and its windings deliver up to 35.0 Nm of dynamic torque when the drive supplies a peak phase current of 17.7 A. A torque constant of 2.52 Nm/A provides predictable output per ampere during control adjustment. Continuous heat is removed by natural convection, so no blower or liquid cooling circuit is required. Position data comes from an optical single-turn absolute encoder that provides high-resolution feedback over one mechanical revolution to the IndraDrive controller chain. Shaft power is transmitted through a 10 × 8 × 45 mm key. The IEC-compliant B5 housing supports flange mounting, while a DS M10 centering hole assists with alignment during installation.
The motor provides a standstill torque of 10.5 Nm, which supports static loads through energized motor torque when the shaft is not rotating. Rapid acceleration is possible because the rotor has an inertia of only 0.00173 kg·m², limiting the energy that must be exchanged during speed changes. The winding has a thermal time constant of 15 min, allowing the passive cooling path to manage short periods of elevated load without an immediate thermal shutdown. Back electromotive force rises at 155 V/1000 rpm, providing the control electronics with the voltage feedback needed for field-oriented regulation. The integrated arrangement reduces power-cable routing between the motor and drive electronics while retaining closed-loop control at the machine axis. Its flange-mounted housing also allows the unit to connect directly to compatible gearboxes, couplings, or machine plates without a separate drive enclosure.
