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.
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.
The neodymium magnet has a much stronger power than the popular ferrite magnet.
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.
(Surface permanent magnet synchronous motor: e.g., servomotor, brushless DC motor)
The lengths of the magnetic field lines at the south and north poles are equivalent. Therefore, no reluctance torque that results in rotational force is generated.
(Interior permanent magnet synchronous motor)
Since the magnetic field lines at the south pole side are made longer than those at the north pole side, the magnetic field lines at the south pole will try to shorten like a stretched rubber band contracts, resulting in rotational force due to reluctance torque in the direction indicated by arrow.
Daikin IPM motor efficiency is much higher than that of an induction motor.
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.
Excellent power pack system achieving dramatic factory energy-savings. Super Unit, utilizing the Daikin IPM motor has made a great contribution to preservation for global environment.
Unparalleled energy-saving and high-accuracy servo-based pump PQ control system for press and general industrial machinery.
A fusion of hydraulic and motor/inverter technologies Drastically improved functions on top of the energy saving features of the IPM motor.
Environmentally Friendly Inverter Oil Cooling Unit.
