Safety-First Motors for Elevators & Lifts

When people step into an elevator, they trust their lives to the motor. Our fail-safe brake motors with manual release levers meet the stringent safety requirements of passenger lifts, freight elevators, and dumbwaiters across India.

The Challenge

Why This Application Demands Specialized Motors

Elevator motors carry the ultimate responsibility — human safety. They must deliver butter-smooth acceleration and deceleration for passenger comfort, instant fail-safe braking during power failures with loads suspended, and reliable operation across thousands of daily cycles. Indian elevator installations face additional challenges: voltage fluctuations in commercial buildings, space constraints in existing shafts, and compliance with IS 14665 (Bureau of Indian Standards for lifts and escalators). A motor failure can trap passengers, cause injuries, and bring severe legal liability.

Our Solution

How Sun Star Motors Solves It

Sun Star Motors™ brake motors with gear are specifically configured for elevator and lift applications. The integrated fail-safe braking system engages spring-loaded brake pads within 30ms of power loss, holding the car securely at any floor. The optional manual release lever allows rescue personnel to manually lower a stuck car during emergencies. Our geared motor units provide the high torque at low RPM needed for smooth, controlled car movement. Gear ratios from 10:1 to 50:1 match standard traction machine requirements.

Frequently Asked Questions

Elevator & Lift Motors — FAQs

01What safety features should an elevator motor have?
Essential safety features include: 1) Fail-safe AC brake that engages on power loss, 2) Manual release lever for emergency rescue, 3) Thermal overload protection to prevent winding burnout, 4) Brake wear indicator for preventive maintenance. Sun Star elevator brake motors include all these features and comply with IS 14665 requirements.
02Can Sun Star motors be used for goods lifts and dumbwaiters?
Yes. Our brake motors with gear are used in passenger lifts, goods/freight elevators, dumbwaiters, and service lifts. For smaller dumbwaiters (up to 100 kg capacity), our 0.5-2 HP range is ideal. For freight elevators handling 1-5 tonne loads, our 5-20 HP motors with appropriate gear ratios provide the necessary torque.
03How do I choose the right gear ratio for my elevator motor?
The gear ratio depends on car speed and load capacity. For low-speed freight lifts (0.25-0.5 m/s), use 30:1 to 50:1 ratios. For standard passenger lifts (1.0-1.5 m/s), use 10:1 to 20:1 ratios. Contact our engineering team with your sheave diameter, car speed, and load capacity for a precise recommendation.
