electric motor rotor frozen to stator (rust?), how to loosen? I have a 12v electric pump that's sat in storage for 25 years. When I pulled it out yesterday and tried to test it, the shaft wouldn't turn. Disassembling it showed a fine layer of rust on the rotor and stator and that they are stuck together.
To rewind an electric motor, remove the motor's outer housing and use your hands to pull the armature out of the stator. Then, use a flat head screwdriver to pry open the tabs on the brush pads, and then cut through the wires and pull them out by hand.

The stator is the stationary part of a rotary system, found in electric generators, electric motors, sirens, mud motors, or biological rotors. Energy flows through a stator to or from the rotating component of the system. In an electric motor, the stator provides a rotating magnetic field that drives the rotating armature.
An electric motor be definition products magnetic flux. Any small unbalance in the magnetic or electric circuit of motors is reflected in the axially transmitted fluxes. Electrical characteristics within a motor will change due to asymmetries in the rotor or stator windings, as will the axially transmitted flux.
DC Motors 1. Shunt DC motor: The rotor and stator windings are connected in parallel. 2. SparatelyExcited motor: The rotor and stator are each connected from a different power supply, this gives another degree of freedom for controlling the motor over the shunt.
The stator is the fixed part of an electrical machine. By electric machine we mean both electric motors and electric generators. The moving part of an electric motor is called a rotor.. In alternating current machines the stator is generally in the shape of …
A stator is the static part of rotary electromagnetic devices such as electric motors, alternators, and generators. It represents one of the two primary components of the device, the other being the moving rotor that supplies the working output. Depending on the device design, the stator may act as the armature or the field winding of the ...

Generally speaking, electric motors consist of a rotor, a stator, windings, an air gap, and a commutator. Rotor In this context, the rotor is a moving part that delivers mechanical power when it moves the shaft. To achieve this turning motion, the rotor is usually designed with built-in current-carrying conductors that interact with the ...
Austin Hughes, Bill Drury, in Electric Motors and Drives (Fifth Edition), 2019 9.8.2 Segmented core and concentrated windings For high pole-number stators, splitting the stator core into segments has obvious attractions both in terms of automated coil assembly and reduction of waste in comparison with conventional (full circle) laminations: a ...

Stator and Rotor. An electric motor is a device which converts an electrical energy into a mechanical energy. This mechanical energy then can be supplied to various types of loads. The motors which are all operating under DC supply is called DC motor. The motors which are all operating under 1Φ AC supply or 3Φ AC supply is called AC motor.
electric motor - electric motor - Construction of induction motors: The stator frame consists of laminations of silicon steel, usually with a thickness of about 0.5 millimetre. Lamination is necessary since a voltage is induced along the axial length of the steel as well as in the stator conductors. The laminations are insulated from each other usually by a varnish layer.
The motor stator recycling machine is designed to recover the copper from scrap electric motor stators. The BMC-20 Winding Puller can efficiently dismantle scrap motor stators with a diameter ranging in 3 inches to 20 inches.

In the electric motor market this can present unforeseen challenges for stator mounts caused by differences in the thermal expansion coefficients. For example; the aluminium housing will expand at a higher rate than the iron-based stator when system temperatures increase.
Induction Motor. The induction motor is one of the types of elector motors that is probably the most widely used for industrial applications. The stator is magnetized due to its connection to the power grid, then the magnetic field induces a voltage and hence a current in the rotor windings, then the induced current in the rotor produces another magnetic field, and then the interaction …
Electric Motors vs. Generators. Both electric motors and generators are electromagnetic devices with an armature winding or rotor, which rotates within a field winding or stator; however, they have opposite functions. Generators convert mechanical energy into electrical energy while motors convert electrical energy into mechanical energy.

The stator working principle is, because of the 3-phase supply, it will generate the rotary magnetic field. The function of this will change based on machines like motor, generator, and fluid powered devices. In the motor, it provides a rotary magnetic field to drive the rotary armature. In a generator, it changes the rotary magnetic field into ...
