VFD variable Frequency Inverters Speed controller

Tesech  Series Frequency Inverters

1.0Outstanding Features

1)Description

Frequency Inverter is an equipment for controlling the speed of a rotational or linear alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor.

2)Application

Frequency Inverter are used in a wide number of applications to control pumps, fans, hoists, conveyors, and other machinery.

3)Advantages

AC motor-driven applications that do not require full speed can save energy by controlling the motor with a variable speed drive. Energy cost saving with variable torque can be significant, often paying for the cost of VFD within a matter of months. In variable torque applications such as fans and blowers, the torque required varies roughly with the square of the speed, and the horsepower required varies roughly with the cube of the speed, resulting in a large reduction of horsepower for even a small reduction in speed. The motor will consume only 25% as much power at 63% speed than it will at 100% speed. This is referred to as the affinity laws, which define the relationships between speed, flow, torque, and horsepower.

The Frequency Inverter provided by us are high quality and can be used in many harsh environment.
