Product Description:
The KA850XXX is a brushless servo motor produced by Sanyo Denki and supplied through the K SANMOTION Servo Motors series. Developed for closed-loop positioning in industrial pick-and-place units, material feeders, and indexing tables, this motor converts DC-bus energy from a compatible drive into tightly regulated shaft motion. A square 88 mm mounting flange allows direct coupling to gearheads or machine frames, simplifying installation in compact enclosures while maintaining the alignment accuracy required by automated production equipment.
At its rated operating point, the motor produces 0.5 kW of mechanical power while turning at 2500 rpm. Under these conditions, it supplies a continuous shaft torque of 1.91 N·m from a DC link of 80 V and a phase current of 7.4 A. The copper windings have an armature resistance of 0.53 Ω and an inductance of 0.86 mH. These electrical properties influence the current rise time, so the associated servo amplifier must use a suitable pulse-width modulation frequency to prevent overshoot. A voltage constant of 30.0 × 10−3 V/rpm indicates the back electromotive force that the controller must overcome as the motor speed increases.
For static and transient loading, the drive can rely on a continuous stall torque of 2.16 N·m and a peak stall torque of 16.7 N·m, providing additional capacity for short acceleration demands. A torque constant of 0.286 N·m/A relates commanded current to produced torque, while the rotor inertia of 6.0 × 10−4 kg·m² moderates speed changes so the axis can follow trajectory commands without excessive vibration. The housing has an IP43 protection rating, which guards against solid objects larger than 1 mm and water sprayed at angles up to 60 degrees from vertical. The assembled motor weighs 4.1 kg, making it suitable for installation on moving carriages where component mass affects axis response.
