Product Description:
The KA850TXX is a DC brushless servo motor produced by Sanyo Denki for the K SANMOTION Servo Motors series. It serves as a drive element for mid-power positioning or speed-regulated axes in pick-and-place machines, small conveyors, and packaging tooling. Operating from low-voltage DC supplies, the motor produces controlled rotary motion that a drive amplifier regulates through current loops. Its compact design supports installation in machines where available control cabinet and mounting space may be limited.
The motor develops a continuous stall torque of 2.16 N·m, allowing it to hold loads at zero speed while remaining within its thermal limits. During normal operation, it reaches a rated speed of 2500 rpm and delivers a mechanical output of 500 W at the shaft. These operating conditions require an armature current of 7.4 A. The three-phase winding has an armature resistance of 0.53 Ω, which influences copper losses and drive selection. For rapid acceleration, the unit can supply a peak stall torque of 16.7 N·m for brief intervals before its thermal limits are reached. The power stage is matched to 75 VDC class inputs, allowing connection to compatible battery-backed or rectified industrial buses without additional conversion hardware.
The motor uses an 88 mm square mounting flange, and its rotor inertia is limited to 6.0 × 10⁻⁴ kg·m². This low rotor inertia supports responsive speed changes with minimal overshoot in properly adjusted servo loops. The windings have an armature voltage rating of 80 V, allowing operation with drives in the same voltage class. The motor has an overall mass of 4.45 kg, making it suitable for installation on moving carriages without placing excessive load on linear guides. An internal tachogenerator provides real-time velocity feedback, eliminating the need for an external encoder and reducing feedback wiring. This arrangement supports straightforward analog or digital speed regulation through a compatible servo amplifier.
