If only the frequency is changed, the motor will be burned out. Especially when the frequency is reduced, the problem is very prominent. In order to prevent the occurrence of motor burnout accidents, the inverter must change the voltage at the same time while changing the frequency.
For example, in order to halve the rotational speed of the motor, the output frequency of the inverter must be changed from 60 Hz to 30 Hz, and the output voltage of the inverter must be changed from 400V to about 200V.
If you want to use the inverter correctly, you must carefully consider the heat dissipation problem.
The fault rate of the frequency converter increases exponentially with increasing temperature. The service life decreases exponentially with increasing temperature. The ambient temperature rises by 10 degrees and the life of the inverter is halved. Therefore, we must pay attention to heat dissipation!
When the inverter is working, the current flowing through the inverter is very large, and the heat generated by the inverter is also very large. The influence of the heat generation cannot be ignored. Generally, the inverter is installed in the control cabinet. We need to know what the heat output of a frequency converter is. It can be estimated by the following formula:
Approximate calorific value = Inverter capacity (KW) × 55 [W] î ‹î ‹ Here, if the inverter capacity is based on constant torque load (overcurrent capability 150% * 60s) î ‹î ‹ If the inverter has A DC reactor or an AC reactor, and also inside the cabinet, will generate more heat. It is better to install the reactor on the side of the inverter or above.
At this time, you can use the estimation: Inverter capacity (KW) × 60 [W] î ‹î ‹ Because the hardware of each inverter manufacturer is similar, the above formula can be used for each brand of products. î ‹î ‹Note: If there is a braking resistor, Because the braking resistor has a large amount of heat dissipation, it is best to install the position separately from the inverter, such as on or near the cabinet.
Other Custom Headers Overview
Custom Headers provide design flexibility, production efficiency while decreasing needed equipment assets
Antenk custom header family offers complete design flexibility to modify standard headers or develop new customized connectors to meet specific design requirements. Use the Custom Header Configurator or contact Antenk to find a custom header solution that caters to a wide variety of programs and volumes.
When OEMs perform pin insertion onto PCBs, they need to invest in stitching machinery to do so, and that increases manufacturing costs. Custom Headers make pin insertion unnecessary and eliminate the need for customers to invest in stitching machinery.
OEMs often look for ways to simplify their manufacturing processes to reduce costs and get products to market more quickly. Custom Headers reduce steps manufacturing process by providing headers with pins already inserted.
While press-fit headers typically meet automotive standards, the interface isn`t the most robust available. Soldered termination not only meets automotive standards, it also provides a stronger interface than press-fit.
