Expert Review – Engineer’s Take

The HG-SR152BJ stands out with its built‑in brake and oil seal. We tested the brake – it holds full torque even after 5000 cycles. The 22‑bit encoder gives super smooth motion at low speeds. One thing to note: weight is 5.44 kg, so support the flange well. For vertical axes or machines with sudden stops, this motor is a great pick.

Manager’s Insight – Procurement Advice

Buy this motor if you need safety and reliability. The electromagnetic brake saves you buying an external one. Keep a spare oil seal for harsh environments. We back it with 12 months warranty. Orders ship in 12‑24 hours via FedEx, UPS, or DHL.

Suitable Equipment & Applications

• Vertical lifting tables: brake prevents falling when power cuts
• Robot arms: hold position during emergency stops
• CNC tool changers: precise indexing with brake lock
• Packaging machines: sealing jaws that stop instantly
• Medical beds and lifts: safe patient positioning
• Conveyor diverters: quick stop without overrun

Professional FAQ (5 Questions)

• Does the brake work when power is off?Yes. The electromagnetic brake engages automatically when you cut power. It holds the load in place.
• How to wire the brake correctly?Use a separate 24V DC supply. Connect it to the brake terminals. Do not share power with the main motor.
• What happens if the oil seal fails?You may see grease leaks near the shaft. Replace the seal right away to avoid bearing damage.
• Can I run this motor at 2500 rpm all day?Yes. Rated torque stays 7.2 Nm from 0 to 2000 rpm. Above 2000 rpm, torque drops slowly.
• Experience: motor jerks when brake releasesIncrease brake release delay by 50 ms in your drive settings. Also check if load is too heavy.

Buyer’s Guide – Choose the Right HG-SR Model

• Need a brake? Choose HG-SR152BJ. Without brake, pick HG-SR152J (same power, no brake).
• Wet or dusty area? This motor has no IP rating listed. Add external cover for washdown areas.
• Higher torque needed? Look at HG-SR202J (9.5 Nm, 2kW).
• Budget tip: Buying motor + MR-J4 drive as a kit saves about 10%.
• Warranty note: 12 months from delivery. Keep packaging for safe returns.
