Product Description:
The KSD071C-0240-NN-S1-1G2-NNNN is a motor-integrated drive unit produced by Bosch Rexroth Indramat for the KSD IndraDrive Mi Motors series. By combining power electronics with a permanent-magnet servo stage, it removes the need for separate panel-mounted drives and allows axes to be positioned directly on moving machine elements. It is intended for decentralized automation where compact drives simplify wiring and enable modular conveyor, packaging, or handling stations. This arrangement places the power section near the load, which can shorten cable runs and reduce cabinet complexity in distributed machine layouts.
This model delivers a continuous torque of 10.5 Nm at rated thermal conditions, providing steady output for prolonged duty cycles. During short acceleration or shock events, the motor can reach a peak output of 35 Nm, and the inverter section supports up to 17.7 A of phase current to produce that transient torque. Rotor dynamics are influenced by an inertia of 0.00189 kg·m², giving a balance between rapid speed changes and mechanical stability. When power is removed, a holding brake applies a static torque of 16 Nm to keep vertical or suspended loads from drifting. These values help match the unit to driven-load inertia, coupling behavior, and the response required by the motion profile.
The brake is electrically released and is powered from a DC 24 V line, so the clamping force is removed only when a control signal energizes the coil. Position feedback uses an optical single-turn encoder that communicates over the Hiperface interface. Its code disk generates 128 sinusoidal signal periods per revolution, allowing fine interpolation inside the drive controller. The motor uses a plain output shaft for clamp-style couplings, and the shaft is fitted with a sealing ring to block coolant or dust from entering the front bearing cavity. This combination supports closed-loop motion while helping protect the mechanical interface during industrial operation.
