If a motor slowed to a halt, will the current go up or down

When not rotating, it has a considerably higher current. ## \\ ## I think @jim hardy is our expert in this area. Perhaps he can also give an input.
You didn't answer his question about whether this is homework.jojo13 said:Yeah, I was thinking the current would then increase
that's exactly the case.Charles Link said:Please correct me @jim hardy if this is not the case:
An electric motor works by converting electrical energy into mechanical energy. This is achieved through the interaction of magnetic fields generated by the flow of current through a wire or coil, and permanent magnets. The flow of current creates a force that causes the motor to rotate, converting the electrical energy into mechanical energy.
The main components of an electric motor include a stator, rotor, and commutator. The stator is a stationary component that contains the magnets or magnetic fields. The rotor is the rotating part of the motor, usually made of copper or aluminum wire coils. The commutator is a mechanical switch that controls the flow of current to the rotor, allowing it to rotate.
There are several types of electric motors, including DC motors, AC motors, single-phase motors, and three-phase motors. DC motors are powered by direct current and are commonly used in household appliances. AC motors are powered by alternating current and are used in industrial equipment. Single-phase motors are used in smaller applications, while three-phase motors are used in larger industrial applications.
There are many advantages to using an electric motor. They are efficient, reliable, and have a long lifespan. They also produce no emissions, making them environmentally friendly. Electric motors are also easily controllable and can be used in a variety of applications, from household appliances to industrial machinery.
If an electric motor is not functioning properly, there are a few steps you can take to troubleshoot the problem. First, check for any loose connections or damaged wires. Next, make sure the power source is working correctly. If these do not solve the issue, you may need to check the motor's components, such as the brushes or bearings, for any signs of wear or damage. If the problem persists, it may be best to consult a professional for further assistance.
