![]() BRAKING UNIT LSBR MODE |
|
| Production Introduction: | |
| We
are a specialize manufacturing factory of motor inverter and electric
type brake . We have been continuous developing new creation and innovation
more than 10 years to enhance best quality and satisfy customer's demand.
When inverter driving motor in high speed rotation and attempting to decelerate motor to motionless situation, as the relation of GD2 there is re-generation voltage flow into DC BUS terminal of inverter and make over voltage. In order to avoid breaking down of machine, the braking unit and braking resistor are playing important roles. The brake components are detecting voltage value and release more balance energy through braking resistor to keep normal voltage and avoid inverter breaking down. |
