1-1. Notice
In the instruction manual, only the differences between 0.2kW and 0.4kW high efficiency motors
are recorded. Please use it together with the following standard manual.

1-2. Notice for adoption to the premium efficiency motor (IE3)
(1) The motor size is larger than IE1 motor.
Please confirm the dimensions of the combination and the interference with the peripheral
equipment during installation.
(2) The rated speed of the motor increases.
When replacing the current product, the rated speed of the motor increases depending on the
purpose of use, so the power consumption tends to increase. (When the motor is operated directly by
commercial power supply.)
(3) The starting current tends to be larger.
To recheck the capacity of electrical devices, such as circuit breaker, magnetic contactor, relay,
and so on, may be needed.
(4) The torque generated by motor tends to be larger.
Recheck the strength of customer’s equipment, due to increasing potential motor output power.
(5) In the case of any load fluctuation, such as compressor, textile machine, etc.
The generation of heat tends to be larger by the rotational speed fluctuation. The inertia of
driven equipment including load fluctuation should be reconsidered.
(6) Regarding the motor
Motor rotational speed
The rated rotational speed of the motor will be higher than the previous IE1 motor, because the
premium efficiency motor (IE3) has low slip due to controlling the loss on the motor.
Ex) The rated rotational speed: from 1710 to 1740 r min
Motor current
The starting torque and starting current on the premium efficiency motor (IE3) will increase
compare with previous IE1 motor, because the coil resistance is designed at lower for dropping
copper loss. Therefore, redesigning of device in the control box, such as the circuit breaker, and
size change of reducer capacity may be needed.
Energy consumption
The energy consumption may be increased, because the motor output power is increasing,
though the motor efficiency is high.
Ex) The motor output power will be increasing, in the case of such as the load in the pump
application. (The load using pump for liquid will increase proportional to cube of
rotational speed) Because the rotational speed of motor will increase by replacing to the
premium efficiency motor.
(7) Please check the following points, when the motor is operated directly by commercial power
supply. In the case of inverter operation, can be used as before.
Check the gear ratio, when the actual speed on previous IE1 motor cannot be increased.
Check the service factor and reducer size, in case of frequent starting and stopping
application.
Check the motor capacity, in the case of continuous operation with light loads.
