Motor controller and protector unit |
摘要 |
A motor controller unit of the type providing optimum motor operation and protection is configured to determine phase rotation correction during motor start-up without stopping and re-configuring. The effects of heat on the squirrel cage (amortisseur) and motor field windings are accurately and automatically determined on a continuing basis to deter nuisance trip occurrence during motor start and restart operations and to prevent damage to the motor windings during continuous motor operation, respectively.
