Expert Review
The HG-KR23J is a top choice for small but fast axis control. Its 22-bit encoder removes the need for home sensors. Low inertia allows quick direction changes without overheating. For 200W applications, this motor delivers reliable, precise motion.
Manager’s Insight
Buy this motor when you need high speed and small size. It works best with Mitsubishi MR-J4 series drives. The natural cooling keeps maintenance low. Use the oil seal version for light machining or dusty areas. With 12-month warranty and 12-24 hour shipping via FedEx/UPS/DHL, it is a safe investment.
Applications & Compatible Equipment
- Pick-and-place robots – fast up/down motion
- Small CNC machines – tool changers or auxiliary axes
- Labeling machines – precise rotary indexing
- 3D printers (industrial) – high-speed extruder drive
- Medical sample handlers – quiet, accurate positioning
- Pairs with 3300 5mm Proximity Probes for position verification in harsh environments.
Professional FAQ
- Does this motor work without a battery?No. The absolute encoder needs a battery to keep position when power is off.
- Can I use HG-KR23J with a 400W drive?Yes, but set the drive current limit to 1.3A to protect the motor.
- What is the difference between HG-KR23J and HG-KR23B?The J model has an oil seal. The B model does not.
- How long does shipping take?Orders ship in 12-24 hours. Delivery takes 2-5 days with FedEx, UPS, or DHL.
- What if the motor fails after 11 months?Contact us. The 12-month warranty covers repair or replacement.
Selection Guide
- Check your load torque: must be under 2.2 Nm peak.
- Match with a 200V class servo drive (MR-J4 series recommended).
- For wet or dusty areas, choose the J version (with oil seal).
- Need more torque? Look at HG-KR43J (400W).
- Always use a shielded encoder cable for noise immunity.
