Electric motors for explosive atmospheres instructions. A motor which can be operated either on dc direct current or on single phase ac alternating current is called a universal motor. Universal motors are known to sometimes overspeed when run with no load. What is common to all the members of this family is that the basic physical process involved in their operation is the conversion of electromagnetic energy to. Download literature related to our electric motor products and learn more about the industries we work in. If the polarity of the line terminals of a dc series motor is reversed, the motor will continue to run in the same direction. A universal motor has a high starting torque and variable speed characteristics. If you would like to speak with one of our staff clinicians, please call 1. An uncompensated universal motor will lose most of its power. When current flows in the field winding, it produces an electromagnetic field.
When the universal motor is fed with a dc supply, it works as a dc series motor. Universal motors are so named because they can run both on ac as well as dc. Sparking at the brushes will also be markedly worse. We have been designing and manufacturing universal motors for leading oems since the 1930s when our company began. It delivers a high starting torque, its speed can be adjusted, it is small in size, and it is inexpensive. Tour series sonar ready adapter listing motorguide. Objectives when you have completed this chapter, you will be able to do the following.
These motors are generally series wound armature and field winding are in series, and hence produce high starting torque. The universal motor is a special kind of ac series motor that performs almost as well as a dc motor. Capacitor motor universal motor shadedpole motor fig. Stator motor universal dapat berupa sepatu kutub salient pole maupun stator silinder non salient. This unwanted induced current is also called eddy current.
My original aim was to bridge the gap between specialist textbooks which are pitched at a level too academic for the average user and the more prosaic handbooks, which are full of useful detail but provide. The universal motor is a type of electric motor that can operate on either ac or dc power and uses an electromagnet as its stator to create its magnetic field. As with the stator, also the rotor core consists of electrically laminated steel sheets. What is common to all the members of this family is that the basic physical process involved in their operation is the conversion of electromagnetic energy to mechanical energy, and vice versa. For a rotary electric motor to work, there must be two magnetic fields, one associated with the stator and the other with the rotor. This conversion is usually obtained through the generation of a magnetic field by means of a current flowing into one or more coils. Such motor runs at dangerously high speeds during no load. Types of electric motors electric motors dc motors other motors h ac motors s unt motor separately excited induction motor stepper motor motor brushlessdc motor series motor hysteresis motor permanent magnet dc pmdc synchronous motor reluctance motor compounded motor universal motor. Depending on the process data, the speed can be reduced in the case of low load requirements in.
