HYBRID ASSEMBLIES / IPM MOTOR
The heart of the HYBRID technology is the DAIKIN IPM motor – a built-in magnet-type synchronous motor – equipped with multi-functional software and electrical inverter controller. DAIKIN introduced the IPM motor into residential air conditioners first in the industry, and also into air conditioners for business use. DAIKIN is recognized worldwide as a top runner in energy-saving air conditioners with over one million installations. This same unique technology has been adapted to oil hydraulic equipment.
Features of the high-efficiency IPM motor and fusion of oil hydraulics and motor/inverter technology:
High-efficiency IPM motor
DAIKIN’s innovative IPM motors are the key technology to energy-saving in air conditioners with over one million installations. This same unique technology has been adapted to oil hydraulic equipment.
“Double Torque, power of rotations” improves the energy saving effect .
The combination of two rotating forces of the ever potent neodymium “magnet torque” and DAIKIN original “Reluctance torque”, elevated power can be generated at lower electricity.
Principle of IPM motor
A rare-earth permanent magnet deeply positioned in the rotor can generate magnet torque (attraction/repellence between coil and permanent magnet) and reluctance torque (coil attracts iron) greatly. This electromagnetic structure attains high torque and the highest efficiency/low heat generation.
Comparison of motor efficiency
Daikin IPM motor efficiency is much higher than that of an induction motor.
High torque at the low speed range
Daikin IPM motor produces high torque at low speed. During general use, an inverter type may at times have limited torque at low speed range; Daikin IPM motor is free of such a problematic occurrence.
Fusion of oil hydraulics and motor / inverter technology
Energy-savings of more than 50% (In comparison of a conventional hydraulic system to our product while when pressure is retained).
The dramatic energy-savings is realized by reduction of the motor rotating speed under retained pressure condition.
The high-efficiency IPM motor will achieve energy-savings even in the general industrial machine field where the operation ratio of actuators is high.
