Basic System Description

A motor control system will obviously include a motor and inverter, as well as a circuit breaker or fuses for safety. If you are connecting a motor to the inverter on a test bench just to get started, that’s all you may need for now. But a system can also have a variety of additional components. Some can be for noise suppression, while others may enhance the inverter’s braking performance. The figure and table below show a system with all the optional components you might need in your finished application.

installer must refer to the NEC and local codes to ensure

 

safety and compliance.

Input-side

This is useful in suppressing harmonics induced on the

power supply lines and for improving the power factor.

 

WARNING: Some applications must use an input-side AC

 

Reactor to prevent inverter damage. See Warning on next

 

page.

Radio noise filter

Electrical noise interference may occur on nearby

 

equipment such as a radio receiver. This magnetic choke

 

filter helps reduce radiated noise (can also be used on

 

output).

DC link choke

Suppress harmonics generated by the inverter. However, it

 

will not protect the input diode bridge rectifier.

input).

Output-side

This reactor reduces the vibration in the motor caused by

the inverter’s switching waveforms, by smoothing the

 

waveform to approximate commercial power quality. It is

 

also useful to reduce harmonics when wiring from the

 

inverter to the motor is more than 10m in length.
