Reduced Torque Ripple for a Comfortable, Smooth Ride
The gearless traction machine with the new PM (permanent magnet) motor is packed with cutting-edge technology, such as our unique stator-core structure and built-in double brakes. This optimized motor design dramatically reduces the level of torque ripple for smooth and quiet ride.

Ensuring that Quality Remains First Rate
Our elevators include features designed to reduce the need for maintenance - such as double brakes built into the PM motor. During scheduled maintenance, equipment in the top of the hoistway is easily accessible from the maintenance platform on top of the elevator cage. In addition, Mitsubishi Electric's highly trained service personnel continually ensure that our elevators run smoothly and safely.

Advanced Door Controls
VVVF* Inverter Control has been adopted to ensure smoother and quieter door operations, thereby enhancing passenger safety and product reliability. Our innovative door operation system employs a highly efficient "One-chip RISC microcomputer" which detects the constant variations on each floor in the door load, the strength of the wind, and even sediment in the sill grooves. It adjusts the door open and close speeds, as well as the door motor torque as needed for each floor using the Auto Tuning function. The learning-capable Door Load Detector immediately reverses the doors when abnormal load is detected on the doors.
*VVVF: Variable Voltage Variable Frequency.

High-Speed Computer Processor
The high-accumulation LSI integrating digital control circuitry has significantly increased the speed of the computer processing, enabling precise control of the traction motor during acceleration and deceleration. This innovation delivers a quality ride with the least noise and vibration.

Innovative Technology Enhances Efficiency and Reliability
More technological advances, such as the high-accumulation LSI and low-noise PWM inverter, enable the VVVF inverter to deliver smooth, high-precision control of the traction machine. In addition, the IPU (Integrated Power Unit) acts as a high-efficiency power supply circuit for the motor drive and, along with the PM motor, delivers greater energy savings. The adoption of the low-noise IGBT with faster switching speeds also contributes to further reduce the noise. The result is a more efficient, more reliable drive control.
The slim control panel is packed with advanced technologies such as VVVF, PWM and IPU.
