The Mitsubishi HF-SP102 belongs to the HF-SP series within the MELSERVO-J3 ecosystem, optimized for medium-inertia loads requiring stable torque and high response. It delivers 1 kW rated output with 4.77 Nm continuous torque (14.3 Nm maximum) at 2000 rpm rated speed (up to 3000 rpm maximum), making it ideal for general-purpose axes in packaging machines, conveyors, printing equipment, and light industrial automation. The medium rotor inertia provides smooth acceleration while maintaining fast settling times for positioning tasks.
Electrical specifications include rated current of 5.3 A (15.9 A peak) on 3-phase 200-230 VAC supply, with power rating at continuous torque of approximately 4.87 kW/s. The integrated 18-bit incremental encoder (resolution: 262,144 pulses/rev) ensures precise speed and position feedback, supporting advanced servo functions like vibration suppression and auto-tuning when paired with compatible MR-J3 amplifiers. The motor features a straight shaft without key and no electromagnetic brake or oil seal in standard configuration, with Class B insulation and totally enclosed non-ventilated IP67 structure for harsh environments.
With compact dimensions (approximately 100 mm frame) and weight around 6-7 kg, the HF-SP102 fits tight machine designs while offering permissible instantaneous speed up to 6900 rpm and maximum torque 3x rated. It’s fully compatible with Mitsubishi’s servo ecosystem for network integration and one-touch tuning.
