AC Induction Motor
YC-70 Electric Brake Motor — 70mm Frame, 15W / 20W
110V / 220V · 15W / 20W · Gear Ratio 1:3 – 1:860
The YC-70 Electric Brake Motor integrates a fail-safe electromagnetic braking system into a 70mm AC gear motor. On power interruption, the spring-loaded electromagnetic brake engages within 50ms, locking the output shaft and preventing unintended load movement. Available in 15W and 20W with up to 1:860 gear ratio, it is the preferred choice for vertical load handling, positioning systems and safety-critical automation.

Frequently Asked Questions
Common questions about the YC-70 Brake AC gear motor
How does the electromagnetic brake work?+
When power is applied, an electromagnet releases the spring-loaded brake disc, allowing the motor to run freely. When power is cut, the spring clamps the brake disc against the rotor, locking the shaft within 50ms.
Can the brake be released manually?+
Yes. Most configurations include a manual release lever for maintenance or emergency shaft positioning without power. Please specify this requirement when ordering.
Is the brake suitable for vertical load applications?+
Yes. This motor is specifically designed for vertical loads such as hoists, lifts and inclined conveyors where preventing load drift on power-off is critical.
What is the brake holding torque?+
Brake holding torque varies by model. Please contact us with your load specification and we will confirm the suitable model and holding torque rating.
