System and method for stall detection of a motor |
摘要 |
A motor starter system comprises solid state switches for connection between an AC line and motor terminals for controlling application of AC power to the motor. A voltage sensor senses AC line voltage and the motor terminal voltage. Current sensors sense motor current. A control circuit controls operation of the solid state switches. The control circuit limits switch current during a start mode and detects a stall condition responsive to sensed AC line voltage and motor terminal voltage and selectively boosts motor current during the start mode if a stall condition is detected.
