The soft start should not cause any damage if properly set up. A properly set up soft starter will permit a motor to reach full speed almost as fast as a DOL starter but will reduce peak current. This is a good thing as it reduces the energy input into the motor during start-up.
I suspect that the energy-limiting feature not being properly set up is causing the failures.
The energy-limiting feature should not slow the motor down. It does not change the frequency. It has the purpose of reducing the iron losses of the motor. The Iron losses are greater than necessary on a lightly loaded motor. Also if the mains supply is higher than nameplate rating the iron losses are higher than necessary.
The optimiser should reduce the voltage by chopping it to the "optimum" level for the operating conditions of the motor.
If properly set up the optimiser will produce some savings on a lightly loaded motor & very little on a fully loaded motors.
A refrigeration compressor is either practically fully loaded or off. Therefore the optimiser will provide very little (if any) savings.
The only soft starter I have used I put on a motor that was really oversized for the power required, mostly because the gearbox it drives had to have a certain size shaft, even though the power to the load is a small fraction of the motor power. The soft starter replaced a star delta switch, and I adjusted it for the slowest ramp possible ( 8 secs), and left the motor to start DOL via the soft starter. Reduced switch on surge a lot, and enabled me to use a much smaller breaker on the feed. Soft starters have a good use, but are not for all applications, they need to be matched to the load character if installed, and this may not be possible for all motors. |
