Curiously, the stators for the 3-phase induction motor and the DC brushless motor are virtually identical. Both have three sets of “distributed windings” that are inserted within the stator core. The essential difference between the two machines is with the rotor.
Ohio Electric Motors indicates that the main difference between AC and DC motors is the power source. AC motors are powered by an alternating current while DC motors use a …
The discussion below on these various motors is generally invertible (at least for DC and AC synchronous devices) to cover both motors (electrical power in, mechanical power out) and generators (mechanical power in, electrical power out).

A DC motor is not the same as a “gear motor” – a “gear motor” may be an AC or DC motor coupled with a gearbox or transmission. A gear motor adds mechanical gears to alter the speed/torque of the motor for an application. Usually such an addition is to reduce speed and increase torque. A DC motor without gears is useful in many applications, for example the simple fan. Contrast that with the
1. check the terminal box ( 3 for AC, 4 for DC and has 2 terminals, then it may be either a 1-phase AC machine or a DC machine) . 2. Check if commutator is present than its a DC motor.
AC unlike DC flows first in one direction then in the opposite direction. The most common AC waveform is a sine (or sinusoidal) waveform. Sine waves are the signal whose shape neither is nor altered by a linear circuit, therefore, it is ideal as a test signal. In discussing AC signal, it is necessary to express the current and voltage in terms of maximum or peak values, peak-to-peak values
a brushed DC motor involves tradeo s between power, speed, and repair frequency/cost. One obvious application for brushed DC motors is in the cheapest of all motors, small lightweight low-power essentially disposable motors that power cheap battery powered devices (e.g. toys). These cost a few dollars at most and wear out relatively quickly but are then just thrown away. These simple motors
AC induction motors have an inherent adhesion advantage over a DC series motor. The AC motor has a steep torque-speed curve when run at a given frequency. A little bit of slip will cause a significant reduction in torque, where the same amount of slip with a DC motor will cause little reduction in torque (and keeps slipping).

Brushed DC Motors Vs. Brushless DC Motors Motion Control

a DC capacitor FIGURE 14.1a Chapter 14 CAPACITORS IN AC AND DC CIRCUITS So far, all we have discussed have been electrical elements in which the voltage across the element is proportional to the current through the element (i.e., elements like the resistor that obey Ohm’s Law). There are electrical elements that do not follow this pattern. One of these elements is the capacitor–a critter that
What is the Difference Between Brushed and Brushless DC Motors? A brushed DC motor uses a configuration of wound wire coils, the armature , acting as a two-pole electromagnet. The current’s directionality is reversed twice per cycle by the commutator , a mechanical rotary switch.

The awkward little block that’s in between the wall plug and your computer is a power adapter that transforms AC to DC. Berggren explains that AC became popular in the late 19th century because of its ability to efficiently distribute power at low voltages.
For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors.
alternating current (AC) motors direct current (DC) motors and universal motors. An AC electric motor will not run when supplied with DC current, and a DC motor will not run on AC current; a AC/DC motor will however run on either AC or DC current. One of the main differentiation we can make between
AC induction motor compared to DC drives are becoming more efficient, taking less space, are lighter, simpler in structure, have a longer life and requirement no maintenance.
on the difference between the rotor speed and the fre-quency of the power being applied to the stator winding. The torque supplied by the squirrel cage is at a maxi-mum when ac power is first supplied to the stator wind-ing and decreases as the rotor accelerates until it reaches zero torque when the rotor approaches synchronous speed. The absolute value of the accelerating torque is a function
