Inerter Duty Motors are designed for optimized performance to run with variable frequency drive. The Inverter Duty Motors have independent cooling fan to cool down motor. It can operate for wide speed range without any heating problem.

A standard motor driven by the inverter generates slightly less power than it does. When it is driven with commercial power supply, also, the cooling effect deteriorates in low speed range, then the motor temperature rising increases.
Reduce load torque in the low speed range. Allowable load characteristics of the standard motors are shown in the figure. If 100% continuous torque is required in the low speed range, use an inverter duty motor is reliable.

The Variable Frequency Drives is suitable for any general-purpose application that involves a AC motor, has full of operation functions. Built-in variable digital/analog input functions to suit a wide array of needs. Easy to install and convenient to humanity operating features
