Can small permanent magnet motors be reverse direction if the direction of current flow to the motor is reverse?
Permanent magnet field motors. With a these motors, a permanent magnet is used to replace the field coil. DC power is connected via the brushes, to the armature only. Reversing the polarity, will cause the motor to reverse its direction of rotation. It is very common to use a switch to intentionally reverse to the polarity, to allow reversal of the motor if desired.
How can magnets contribute in your society?
Magnets are very important to us. without a magnet there is not even a single electric machine is found....... magnet is used in electronics also for example PC hard disk;windmill,speakers,motors ,generators,etc.........................
What is the difference between crown motors and regular motors?
The difference between crown motors and regular motors is that crown motors is a company, and regular motors are not. Regular motors, are the motors that can be found under a car hood.
What type of motors are used on lifts?
dc series motor
Can ac motor be used in car airconditioner?
In a car the power supply is DC so all motors in cars work on DC. Also, AC motors are usually designed for 120 v or 240 v so they would not work on 12 v DC. So the answer is no.

Does a blender need a electro magnet to work?
Yes, AC motors generate their own magnetic field.
What are the two types of motors?
permanent magnet motors and series motor
How do motors that do NOT use magnets work?
Motors that do not have magnets work exactly the same. The permanent magnet is replaced by a electromagnet, which is a coil of wire with a voltage applied to it. This electromagnet is what produces the magnet field necessary for a motor to operate. It is just easier and lighter to use this style of DC motor in larger applications.
What are the two types of dc motors?
permanent magnet motors and series motor
Where is magnet wire used?
Windings for motors.
Do air conditioners have magnet in them?
yes because they have electric motors in them. electric motors contain magnets.
Does a vacuum cleaner need a magnet to work?
Some kind of magnet or magnetic field is necessary for a motor to operate. Alternating current vacuum cleaners (that plug into the wall) have motors with electromagnets. Direct current vacuum cleaners (that plug into the car's cigarette lighter socket) have motors with permanent magnets.
Which are some of the stores that one might find to buy magnet motors?
As far as can be ascertained from researching this question, there are no stores where one can buy magnet motors as they are not a proven technology. One can, of course buy magnets at many stores.
Where can one find more information about permanent magnet DC motors?
One can find more information about permanent magnet DC motors on the internet and specifically on the website grainger. Moreover, one can find information on ohioelectricmotors.
How do permanent magnet motors work and what are the key principles behind their operation?
Permanent magnet motors work by utilizing the magnetic field generated by permanent magnets to produce motion. The key principles behind their operation include the interaction between the magnetic field of the permanent magnets and the magnetic field produced by the flow of electric current in the motor's coils. This interaction creates a force that drives the rotation of the motor's rotor, resulting in mechanical motion.
