Yes, motor windings can be cleaned with Varsol, which is a type of mineral spirits or solvent. However, it's important to ensure that the motor is completely de-energized and disassembled before cleaning. Additionally, care should be taken to avoid damaging insulation materials. Always follow manufacturer guidelines and safety protocols when using solvents.
To determine whether there are any electrical shorts among windings, or from windings to case ground.
there is a possibility that parts of motor windings has partial damage.

To check a motor's windings for a short circuit, you can use a multimeter to measure the resistance between the winding terminals. A reading close to zero ohms indicates a short circuit, while an infinite or very high resistance suggests the windings are intact. Additionally, you can check for shorts between the windings and the motor frame by measuring resistance from the winding terminals to the frame; any low resistance reading indicates a short to ground. Always ensure the motor is powered off and disconnected before performing these tests for safety.
neither. DC locks the rotor of a stepper stationary, pulses applied to a stepper's windings in one order advances it while in the opposite order reverses it. steppers typically have 4 to 6 windings.
No, you do not need to rinse Varsol after use. Varsol, a type of mineral spirits, evaporates quickly, leaving no residue. However, it's important to ensure that any surfaces or items cleaned with Varsol are well-ventilated and allowed to dry completely. Always follow safety guidelines when using solvents.

The windings of the motor will be gonebecause of high current diectly goes to the windings of motor.
No, it is not necessary to have three-phase rotor windings for a transmitter and motor in a selsyn motor. Selsyn motors typically use single-phase rotor windings to transfer information or control signals between devices. The synchronization between the transmitter and motor is achieved through the interaction of the stator and rotor windings.
A synchronous motor comprises of a stator windings and a rotor with a squirrel cage and inside that is windings(coils). At starting, this motor is an induction motor running with slip. After the rotor has reached a certain speed, a DC current is applied to the windings inside the squirrel cage. A fixed field is induced in these windings. This field locks in with the synchronous rotating magnetic flux of the stator windings. The rotating stator windings then pull the rotor along. The amount of excitation current can be used to control the power factor of the motor, making this a popular type of motor for high power use with a constant mechanical load.
The bimetallic overload protector is mounted in series with the motor windings. Should the current in the motor windings increase to a dangerous value, the heat developed by the passage of the current through the protector will cause it to open. This breaks the circuit to the motor windings and stops the motor before any damage can occur.
The number of windings in a ceiling fan motor generally depends on the motor's design and size. Typically, these motors have multiple windings, which are coils of wire wrapped around the motor's core. The windings create electromagnetic fields that interact with the motor's magnetic components to generate rotary motion.

For a D.C motor it is the field windings which must always be in series with the armature windings.
