SIEI AVY3150-KBL-BR4 15kW Elevator Inverter Drive For Permanent Magnet Synchronous Gearless Motor Elevator Spare Parts

Precision Speed Control
Converts fixed AC power to variable frequency & voltage, controlling traction motor speed for smooth acceleration, deceleration and leveling.
Closed-Loop Vector Control
Works with encoder (PG) feedback for high-precision speed and position control, ideal for gearless synchronous motors.
High Starting Torque
Delivers 200% instant overload torque to prevent car from slipping when fully loaded, ensuring smooth starting.
Perfect Leveling Function
Achieves high-precision floor leveling (±1mm) and supports re-leveling and pre-opening door for efficiency.
Regenerative Braking & Energy Control
Built-in brake unit manages regenerative energy during descent, ensuring fast, stable stopping.
Comprehensive Safety Protection
Monitors over-speed, brake status, contactor status, over-current, over-voltage, under-voltage, over-heat, encoder error, etc.
System Communication
Connects to elevator mainboard via RS485 (Modbus) for command and status exchange.
Fault Diagnosis & History
Detects faults instantly, stops the elevator safely, and stores error codes for quick troubleshooting.
