In the Hall effect circuit, what condition prevents the motor from starting?

The starting condition relies on the Hall-effect sensor acting as a magnetically controlled switch: when a magnetic field is present, the Hall sensor closes the circuit and allows current to energize the motor. If there is no magnetic field, the sensor stays open, so the motor never receives the start signal and won’t begin to run. This is why the absence of a magnetic field is the reason the motor doesn’t start. Other issues, like an overload, a power supply failure, or a latched sensor, would stop or prevent starting in different ways, but they do not explain the required magnetic-field trigger that the Hall sensor depends on.
