Simply put, DC motors can turn in either direction (clockwise or counter-clockwise) and can be easily controlled by inverting the polarity of the applied voltage. Strictly speaking, the motors can actually create a force in either direction.
What happens if you turn a DC motor backwards?
If you try to stop or reverse it manually, then it will try to draw whatever current is needed to continue running at that speed. The high current could heat the motor to the point of damage, unless the power supply limits the current.
Can electric motors go 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.
Do all electric motors spin the same direction?
Electric motors are designed either for clockwise rotation, or counter-clockwise, or both. This is very simple. The IEC standard says that the direction of rotation is always viewed from the driven end side, where the load is.
How much voltage drop does it take to cause problems to a motor?
In general, satisfactory motor performance requires a voltage within ± 5% of its rated nominal value in steady-state operation, Starting current of a motor can be 5 to 7 times its full-load value (or even higher). If an 8% voltage drop occurs at full-load current, then a drop of 40% or more will occur during start-up.
How can a motor spin fast?
One easy way to make the motor run faster is to add another magnet. Hold a magnet over the top of the motor while it is running. As you move the magnet closer to the spinning coil, one of two things will happen. Either the motor will stop, or it will run faster.
