Aug 02, 2017· Construction of a universal motor is very similar to the construction of a DC machine. It consists of a stator on which field poles are mounted. Field coils are wound on the field poles.However, the whole magnetic path (stator field circuit and also armature) is laminated.
Dec 13, 2017· This video will describe the working principle and applications of universal motor, with detail construction and features of universal motor. Share! Support and Subscribe our channel! Youtube Link ...
A universal motor is a special type of motor which is designed to run on either DC or single phase AC supply. These motors are generally series wound (armature and field winding are in series), and hence produce high starting torque (See characteristics of DC motors here). That is why, universal motors generally comes built into the device they are meant to drive.
Jan 06, 2019· AC series motors are also known as the modified DC series motor as their construction is very similar to that of the DC series motor. Before we discuss these modifications, here it is essential to discuss what is the need and where do we need to do modifications.
A universal motor is a series wound electric motor that can operate on both AC and DC power. These are a lot comparative to those of DC series motors but the series motor develops less torque when working from an AC supply than when working from an equivalent DC supply.

Nov 30, 2016· Universal motor is one which operates with both ac or dc supply. its principal of operation is same as dc series motor.Even though the construction of a universal motor is same as a dc series motor it requires some modification in construction,win...
george washington was the first to use and electric motor An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of rotation of a shaft.
Jun 26, 2015· A universal motor contains stator windings and rotor windings. Current in the rotor windings is not strictly the result of inductive coupling as in the induction motor. The defining characteristic of the universal motor with respect to its construction is that the stator and rotor windings are wired in series.
The torque-speed characteristic for the Universal Motor block model is related to the parameters in the preceding figure. When you set the Model parameterization parameter to By DC rated power, rated speed & maximum torque or By DC rated power, rated speed & electrical power, the block solves for the equivalent circuit parameters as follows:
Universal motors also lend themselves to electronic speed control and, as such, are an ideal choice for devices like domestic washing machines. The motor can be used to agitate the drum (both forwards and in reverse) by switching the field winding with respect to the armature.

Universal Motor The motors which can be used with a single phase AC source as well as a DC source of supply and voltages are called as Universal Motor.It is also known as Single Phase Series Motor.A universal motor is a commutation type motor. If the polarity of the line terminals of a DC Series Motor is reversed, the motor will continue to run in the same direction.

Universal Motor - construction, working and characteristics. A universal motor is a special type of motor which is designed to run on either DC or single phase AC supply. These motors are generally series wound (armature and field winding are in series), and hence produce high starting torque (See characteristics of DC motors here).
Jun 21, 2016· Universal Motor – Construction, Working and Application A universal motor is a special type of motor which is designed to run either on DC or single phase AC supply. Universal Motors are so named because they can run both on AC as well as DC.
The shaded pole induction motor has no commutator, brushes, collector rings, contactors, capacitors or moving switch parts, so it is relatively cheaper, simpler and extremely rugged in construction and reliable. The absence of a centrifugal switch eliminates the possibility of motor failure due to faulty centrifugal switch mechanisms.
May 15, 2018· A universal motor is one that can operate on either DC or single-phase AC power supply. It is a series-wound motor, meaning that the field and armature windings are connected in series, and is mechanically commutated with brushes and a commutator.
The same DC machine can be used as a motor or generator. Therefore, theoretically, construction of a DC motor is same as that of a DC generator. Working principle of a DC motor An electric motor is an electrical machine which converts electrical energy into mechanical energy. The basic working principle of a DC motor is: "whenever a current carrying conductor is placed in a magnetic field, it ...
Nov 27, 2019· The three phase induction motor is the most widely used electrical motor. Almost 80% of the mechanical power used by industries is provided by three phase induction motors because of its simple and rugged construction, low cost, good operating characteristics, the absence of commutator and good speed regulation. In three…
