What are the two types of motors?
permanent magnet motors and series motor
What is PMDC motors?
PMDC-Permanent Magnet DC motor is a DC machine where the Permanent Magnets form the stator of the machine instead of conventional Field winding. It works on the same principle of electromagnetic induction.
What are the two types of dc motors?
permanent magnet motors and series motor
Is your washing machine motor an induction type?
Older/cheaper washers all use AC induction motors. Some now use permanent magnet AC motors or "pancake" motors. The pancake motor is a large diameter flat motor that is directly attached to the drum and doesn't require gearing or pulleys. They're often called "direct drive" or "smart drive".
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.
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.
Does a washing machine need a magnet to operate?
The answer is both yes and no.It actually depends on the kind of washing machine in question.The problem is the motion.A washing machine need some kind of an engine or motor in order to move the cloths back and forth. This can of course be done manually.If we rule out manual washing machines, and also only count in electrical ones then these can be made in two different ways.The motor causing the tumbling or the motion in the washing machine can be made with both permanent magnets like NeoDym, or with purely electrical pulses creating strong electromagnetic fields.Most motors in washing machines made today are made without magnets. It is cheaper to make purely electrical motors where the electricity provides the magnetic fields needed. By electronically rotate the magnetic field around the axis, this will force the motion of the motor. It would use less electricity to make the motors with NeoDym magnets but it would also cost more to produce.As a conclusion: We can not make an electrical washing machine that operate without magnetic fields, but magnetic fields does not have to be made by magnets.
Where are dc motors found at home?
Its in computers, air conditioners, bread machine, washing machine, heating machine, soya bean mixer

How does a washing machine works using electromagnetism?
Becasuse magneto-dynamics allow electricity to flow in dc motors in washing machines.. ^^
