Suitable for Uni-directional Continuous Operation
Induction motors are for uni-directional continuous operation such as conveyor belt system.
Ŧ
Meet Safety Standards and Global Power Supply Voltages
The most part of models conform to KS/UL standards and CE Marking. And meets power supply voltages of North America,
Asia and Europe. ; 100V, 110V, 200V, 220V, 230V, 380V, 400V, 440V
Ŧ
Single Phase run
For a single phase motor run, please use the condenser complying with the capacity of that motor.
For a single-phase induction motor, it is not possible to reverse the direction within a short time during operation.
So stop the motor first and change the direction next. (Figure 1.)
Ŧ
Three Phase run
Three phase induction motor has relative higher starting torque comparing single phase and has high reliability
because it can be operated by a three-phase power source directly. (Figure 2.)

Ŧ
The Relation between Speed and Torque
In a condition of constant power voltage, the relation between speed and torque is like right figure.
Under the condition of no-load, the number of rotation roughly is same as the number of synchronous
rotation. But if the load increases, the number of rotation decreases and approaches to the speed (rpm)
indicated by the point P where the torque Tp horizontally meets the load curve.
When the load further increases and reaches the point M, the motor stops at the point R because the
motor no longer generates further torque.
Therefore, the leg R-M is referred to as an unstable zone and the leg O-M is a stable zone for operation.
Ŧ
Feature of Voltage and Condenser
Generally the torque of induction motor changes in proportion to the value of two times the voltage. And it also changes
according the capacity of the condenser.
If the condenser capacity increases, the starting torque and rated torque will increase.
But if the capacity increases by over 2 times, the rated torque decreases and starting torque do not increase.
When the induction motor is short on torque, it is possible to increase the torque by increasing the voltage or the condenser
capacity to continue the operation.
But please be informed that in this case the loss
input of the motor increases and the rapid rise of
temperature would be. However, if the motor must
be run with insufficient torque, take measures to
let the motor release heat as much as possible by
installing separate fan as a example and operate
the motor so that the temperature of the motor's
housing keep below 90œ .
