There are different types of Capacitor-start motors designed and used in various fields. They are as follows:
- Single-voltage, externally reversible type,
- Single-voltage, non-reversible type,
- Single-voltage reversible and with thermostat type,
- Single-voltage, non-reversible with magnetic switch type,
- Two-voltage, non-reversible type,
- Two-voltage, reversible type,
- Single-voltage, three-lead reversible type,
- Single-voltage, instantly-reversible type,
- Two speed type, and
- Two-speed with two-capacitor type.
These motors can be used for various purposes depending upon the need of the user. The starting, speed/torque characteristics of each of the above motors can be analyzed before employing them in work.

Why squirrel cage motor is NOT suitable for use as a DC machine?
A 'squirrel cage' rotor is used in an a.c. inductionmotor, meaning that there is no electrical supply to that rotor with the currents in the rotor , instead, being the result of induced voltages caused by currents flowing in the field windings. A rotor of a d.c. motor, is electrically connected to the supply. The two types of motor work on completely different principles, so cannot use a squirrel cage rotor.
Why rotor contactor in external resistance of slipring motor connected in delta?
rotor contactor are used to cut the resistance in slip-ring motor connected through resistance box. resistance is proportional to torque. so by controlling rotor contactor resistance can be controlled and hence torque can be controlled. for more information check torque and speed characteristic of wound motor.
Type of dc motor used by fan?
Synchronous motor or induction motor
What type of motor is used in ac servometer?
ac motor
What type of motor used under the water?
It is submersible motor.
What is squirrel cage induction generator?
Squirrel cage type is a type of Induction motor. It tells that the rotor is "squirrel cage" type. Another type of induction motor is with "slip ring" type of rotor. Squirrel cage type is most widely used Induction motor.
What are the Types of alternators based on rotor construction?
Types of rotor-Salient pole or projected typeNon salient pole or cylindrical typeSalient type is used for low speed or medium speed motor where non salient type is used for high speed rotor.

What type of motor is used in refrigerator?
stepper motor
How Synchronous motor work with principal?
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.
Why rotor contactor in external resistance of slipring motor connected in delta?
rotor contactor are used to cut the resistance in slip-ring motor connected through resistance box. resistance is proportional to torque. so by controlling rotor contactor resistance can be controlled and hence torque can be controlled. for more information check torque and speed characteristic of wound motor.
What is the difference between a conduction and a induction?
Although the term 'conduction motor' isn't widely used, it refers to a motor whose rotor winding, as well as its stator windings, is supplied with an electric current. In the case of an 'induction motor', however, the current flowing through the rotor is produced by voltages 'induced' into the rotor windings by a rotating magnetic field created by the stator windings.
What type of motor is used in a ceiling fan?
Single-phase motors - These motors are commonly fractional-horsepower types, though integral sizes are generally available to 10 hp. The most common single phase motor types are shaded pole, split phase, capacitorstart, and permanent split capacitor.Figure 5 - Rings in shaded-pole motor distort alternating field sufficiently to cause rotation.Figure 6 - Split-phase windings in a twopole motor. Starting winding and running winding are 90 ° apart.Figure 7 - Split-phase start induction motor.

mini stepping motor
What type of motor is used in ac servometer?
ac motor
