In which device can I find a DC motor?
Small DC motors can be found in DVD or CD players, and the disk drive of a computer.
Why are DC motors used in home appliances?
These modified appliances are more efficient than traditional AC fed appliances. Most of the appliances having rotatory part use universal dc motors or 1-θ induction motors which have low efficiency because of carbon brush and mechanical commutation bearing a major maintenance cost and mechanical losses.

What appliances have brushless motors?
Brushless motors have come to dominate many applications, namely hard drives, CD/DVD players, pumps, fans, robotic vacuum cleaners, coffee machines, mixers, hairdryers, bread cutters and spindle drives in adjustable or variable speed applications.
What can I do with a 12v DC motor?
While smaller DC motors are commonly used in the making of appliances, tools, toys, and automobile mechanisms, such as electric car seats, larger DC motors are used in hoists, elevators, and electric vehicles. A 12v DC motor is small and inexpensive, yet powerful enough to be used for many applications.
What can you make out of an old fan motor?
We bet you’ll want to repurpose your old fan after you see these projects!
How do you make a magnet motor?
Quote from the video:
Quote from Youtube video: You'll want to touch the bent portion of your wire to the top of your battery. Next we want to bend the two ends of our wire. So that they will run directly across the middle of the magnets.
Can I use DC motor as generator?
It may surprise design engineers that both Brushed DC and Brushless DC (BLDC) motors can operate as generators. A brushed DC motor is appropriate for generator applications requiring a DC voltage output, while a brushless DC motor is suitable for AC voltage applications.
Can I connect DC motor directly to battery?
Yes. No need for voltage regulator or similar. Voltage would be ~24V minus some voltage drop on transistors on H-bridge, so it is safe for motor, because this is the voltage the motor is rated for.
Can DC motors spin both ways?
DC motors, like AC motors, can be configured to turn in either direction. Their direction can be easily controlled by inverting the polarity of the applied armature voltage by reversing the armature leads.
What happens if you add more magnets to a DC motor?
Adding stronger magnets can affect a DC motor. Increasing the strength of the DC motor’s magnet will increase the amount of magnetic force generated per Amp of current flow.
Could you create a motor with two permanent magnets?
Many attempts have been made to construct a motor using only permanent magnets to generate the magnetic fields for both the stator and the rotor, but they did not succeed. Such a motor would be powered entirely by the intrinsic magnetic fields generated by permanent magnets.
What happens if a DC motor is connected to AC supply?
If a DC series motor is connected to a ac supply same current will flow through the series field and armature field after being rectified by the commutator. So, the machine will run but with high sparking at brush, poor pf, low speed and low efficiency.
Does a DC motor need a capacitor?
Capacitors are used to reduce interference and noise in DC motor. Capacitors reduce the spikes in the motor current and reduces the magnetic interference. Capacitors are used with DC motors when it is driven by digital signals. The capacitor smoothens the rotation of the motor during the frequent changes in motor load.
Can you connect a DC motor to AC power?
(1) AC motor cannot run on DC Supply because of most of AC motor like Single-Phase Induction Motors, Three Phase Induction Motors, Synchronous Motors need alternating flux, not static flux. As we know that only AC can produce alternating flux. So AC motor cannot run DC supply.
What will happen if DC motor is used without starter?
What will happen if DC motor is used without starter? Explanation: It would cause intolerably heavy sparking at the brushes which may destroy the commutator and brush-gear. Sudden development of large torque will cause mechanical shock to the shaft, reducing its life.
Which of the following motors has the highest no load speed?
DC series motor
No-load speed of which of the following DC motor will be highest? Explanation: At no load, armature current tends to zero, flux φ tends to zero, where speed is inversely proportional to the flux, speed will tend to infinity. Thus, no load speed of DC series motor is highest.
How speed of the DC shunt motor can be increased?
How speed of the DC shunt motor can be increased? Explanation: For a constant load, load current will remain constant. Decreasing armature current will help in increasing speed for DC shunt motor.
