1 Further energy savings with high-efficiency IPM motor installed. The system uses an ultra energy-saving IPM motor*, featuring a combination of magnet torque (pull-in and repulsive force between a coil and permanent magnet) and reluctance torque (pull-in force between *IPM motor: Interior Permanent Magnet Synchronous Motor a coil and iron). Refer to Page 9 for details on the IPM motor. Power consumption 2 Low noise level at 50 dB (A) achieved in the pressure holding mode 3 EcoRich R is excluded from high-efficiency motor regulations. High-efficiency motor regulations came into effect in Japan...

External dimension diagram Do not place any obstacles to oil cooler air intake and exhaust within a distance of 100 mm from end faces of the unit. Install the unit at a location with good air flow so that heated air can be vented and take care about the temperature of the suction air: it must satisfy the stipulated condition for ambient temperature.

EHU15R-M0701, M0702 EHU30R-M0701, M0702 I/O signal terminal block Terminal Terminal code Type Signal name (The above figure shows the normal status of the relay contacts.) * The switching capacity of the contact output is DC 30 V, 0.5 A (at resistance load). * The minimum applicable load of the contact output is DC 10 mV, 10 pA, but this is only a guide to the lower limit where switching is possible with a minute load. The value varies depending on the switching frequency, environmental conditions, etc., so it is advisable to check the actual value.

Energy-saving technology that supports hybrid hydraulic systems Daikin was the first in the industry to introduce an interior permanent magnet synchronous motor (IPM motor) into air conditioners for household use. Daikin was also an early adopter in the industry of the IPM motor for use in industrial-use air conditioners. We have led the industry as a front runner in air conditioner energy-saving performance. “Double torque” improves the energy-saving effect. Combining two rotational forces, “magnetic torque” generated by a powerful neodymium magnet* 1 and “reluctance torque”* 2 , generates...
