HK-KT103W Mitsubishi HK-KT103W servo motor 1 kW, 3.2 N·m, 3000 rpm, 80 mm flange, 26 bit encoder

The Mitsubishi HK-KT103W servomotor from the MR-J5 series is rated at 1 kW with a rated torque of 3.2 N·m, a rated speed of 3000 rpm and a maximum of 6500 rpm. The 80 mm flange motor is fitted with a 26-bit absolute encoder.

• 26-bit absolute absolute feedback — precise positioning and position retention without a homing run after power-up.
• 3.2 N·m rated torque at 3000 rpm — stable effort across the working range of the cycle.
• Speed headroom up to 6500 rpm — dynamic acceleration and short cycles without losing accuracy.
• Standard 80 mm flange — predictable mechanical mating and straightforward replacement.
• Matched to MR-J5 amplifiers — a tuned motor-plus-drive pair within 1 kW.

The motor is used in CNC machine-tool axes, pick-and-place, robotics, packaging and labelling machines, conveyors, textile and printing equipment.

We will match a suitable servo amplifier to HK-KT103W for your control mode. We supply genuine Mitsubishi with CE certification, warranty and engineer-level technical support.

Mitsubishi MELSERVO MR-J5 is the current flagship servo drive series. Its defining feature is a 26-bit absolute batteryless encoder (over 67 million pulses per revolution) that retains absolute position without a serviceable battery, eliminating scheduled replacements and unplanned downtime. The control loop runs roughly 50% faster than the previous generation, with enhanced vibration suppression for clean, stable motion at high speed. Interfaces available: -A (general-purpose pulse/analog) and -B (SSCNET III/H).

MR-J5 pairs with new-generation motors HK-KT (low-inertia, 3000 rpm — for fast, dynamic applications) and HK-ST (medium-inertia, 2000 rpm — for higher torque and medium capacity). Range 0.1–7 kW, 200V class (1-ph/3-ph 220V) and 400V class (3-ph 380V), flanges 40–176 mm, with or without a holding brake. Higher torque density and finer feedback yield better cycle repeatability.

The series fits applications where speed and precision are critical: electronic assembly, pick-and-place, robotics, CNC machine-tool axes, high-speed packaging and printing. We supply genuine Mitsubishi drives with CE certification, select a matched amplifier-and-motor pair for your task, and provide warranty plus engineer-level technical support at every project stage.
