See full version: AC and DC Motors | Types of Electric Motors and Applications
Electric motors play an essential role in almost every industry. Using the right type of motor with high-quality parts and regular servicing keeps your facility running smoothly and prevents damage to the endpoint equipment due to wear or power surges.
Installing and maintaining the right motors in your company’s facilities and equipment is an essential step to ensuring uninterrupted operation and production.
AC and DC motors are broad categories of motors that include smaller subtypes. Induction motors, linear motors, and synchronous motors, for example, are all types of AC motors. AC motors can also include variable-frequency drives to control the motor’s speed and torque, while DC motors are available in self-excited and separately excited-type models. more
The easiest way to know if your golf cart has an AC motor is to read its description online.
Understanding the benefits will make it easier for you to decide if you want to buy one of these carts or if you want to convert one using a kit provided by the proper manufacturer.
That said, they do provide owners with an AC conversion kit they can use to change their DC motor to an AC option.
These sections attach to various rotor windings, producing a magnetic field (dynamic) in the motor when we apply a voltage across the motor's brushes. In terms of DC motor issues, the commutator and brushes are the two most common causes of motor failure due to wear. here
The advantages of the AC motor include minimal maintenance and less demand for power on starting. In general AC motors are efficient, durable, and quiet, thus making them highly desirable for some applications. [links]
Although there are two overall categories for electric motors, and various sub-types, they all share similar components. For example, all motors use a stator comprised of wound, insulated wires or a permanent magnet. Motors also use an armature (rotor) that typically sits in the middle and is subject to the stator's magnetic field. The poles of the armature rotate and are repelled and attracted by the various poles of the stator.
Commutator: When the rotor turns inside the stator, the brushes rub the various sections of the commutator, thus supplying a charge to that section and the corresponding winding. Also, when the brushes pass over the commutator gaps, the electrical charge it provides switches commutator sections or segments. here
Now, as the motor turns, the windings receive constant energization at different sequences to ensure that the magnetic poles produced by the rotor are not overrunning the poles created in the stator. Also, the switching of the field within the rotor's windings is what we refer to as “commutation.” here
DC stands for Direct Current. DC motors have a transformer that connects the supplied wiring and converts it to direct current, which then powers the fan. We won’t get into all the technical details, but the transformer is smart and allows for extra energy efficiency. more
There are plenty of ways to select a fan—its look, size, style, light output, and more. One nitty-gritty consideration is the type of motor you want in your fan. It may seem like a small detail, but motor type affects the bulk and efficiency of the fan. Here’s our expert insight on AC and DC motors.
Disadvantages of DC Motors [links]
This Maverick Fan is an example of a DC motor. It is sleeker because of the small motor, and adds an extra clean look to any fan. [links]
