— See our full range of electric motors here. 1. Electrical Overload. Electrical overload or over-current is caused by an excessive current flow within the motor windings, exceeding the design current which the motor is able to carry efficiently and safely. This can be caused by a low supply voltage, resulting in the motor drawing in more current ...

— Switching between the two values takes place at a pre-defined motor current. This may be used to obtain better tripping performance during starting on motors that use a star-delta starter. During starting, the motor windings carry full line current, while in the 'run' condition, they carry only 57% of the current seen by the relay.

— 4) A fault in the motor. Pretty rare. This can be tested with an ohmmeter. If you don't know the condition of the wiring to the motor, bad ohm readings can be either the wiring or the motor. Based on the drawing you gave, I'll guess that this is a 1-1/2 HP motor. If so, you should have 1.7-2.2 ohms from yellow to black.

— When a motor starts, it typically requires 6 times the full-load current rating. After the motor ramps up to operating speed, the current drops off. Motors are designed to handle this overload condition only for a short period of time. If a motor maintains this overload condition, the motor will overheat and potentially become damaged.

Treadmill Motor Issues: The motor is the heart of the treadmill and is responsible for powering the belt. If the motor is experiencing issues, such as overheating, it can cause the breaker to trip. This can be caused by a lack of lubrication, worn-out bearings, or a damaged belt. To fix this issue, the motor will need to be serviced or replaced.

— The dust collector sits outside and the motor is not enclosed in any part of the dust collector so it stays in a relatively dust free area. The motor sits on top of the dust collector and is totally exposed to the great outdoors. It has been running flawlessly since it was installed and just started tripping the overload a day or 2 ago.

Overload. The term "overload" describes a moderate and gradual rise in the value of current over a relatively long period of time. It is caused by excessive amounts of current drawn by a motor, which may be as high as six times the rated current. This is caused by too much load on a motor. Systems are protected by overload protection relays ...
