High performance and high efficiency PM motorPM Motors for Elevator
Our latest elevator control technologies realize low noise and low vibration.
It enhances elevator value by providing a comfortable ride.
- Low voltage
- Rated voltages are 200 V class and 400 V class.
- It is an AC-driven motor.
- Dedicated model
- It is a dedicated motor for each machinery.
- For variable speed machinery
- It is a motor for variable speed machinery.
- Fully enclosed type
- It has an enclosure that is protected against solid foreign objects of 1.0 mm Ø except the external fan part (IP4X)/.
- Horizontal type
- The installation method is horizontal.
It is a low noise and low vibration motor with drastically reduced torque ripple by adopting a surface magnet PM motor and optimizing the shape of the magnet.
Further, its design factored such matters as malfunctions due to the installation site conditions or the leakage current reduction causing the deterioration of control performance.
As the elevator motor, a series of loading mass 450 kg to 2,000 kg and elevating speed 45 m/min to 105 m/min and a series of loading mass 900 kg to 2,000 kg and elevating speed 120 m/min to 240 m/min are offered as a standard series.
- The rich elevator drive technology resources developed for 30 years.
- An SPM motor is applied.
- A comfortable ride is provided by realizing high torque and low torque ripple.
- No machine room (in the case of the slim PM3T machine)
Applications and Solutions
Our company has been a supplier of elevator motors and control devices since the beginning of the 1970s, and our products are being used in the elevators in many countries around the world and cover a wide range of elevators from low speed to high speed.
The hoisting machines for elevator have various requirements of loading mass, the speed, etc. and our company offers the wide range motor drive units for for elevators: from a mid-to-low speed machine to a super high speed machine.
The elevator has become essential product for our daily life in response to the needs of barrier-free housing and high-rise buildings, etc. It is mainly consisted of a controller (doing elevator operation management), hoist unit (moving the elevator car) and an inverter (controling the hoist motor.)
Recently, the machine room-less elevator systems became common and these systems are being used in many places starting from the train stations, etc.

What is PM motor
The PM motor is a permanent magnet type synchronous motor that does not require any DC excitation. The rotor has the same structure as a cage type induction motor, and it has a built-in magnet to exhibit the performance of a synchronous motor.
Because it can be started with commercial electric power and operated by synchronizing the frequency, highly accurate speed control can be easily performed without feedback control such as encoding.
