Why the DC motor is call as synchronous motor?
A 60Hz synchronous motor spins at synchronous speed - if it's a two pole motor it will spin at exactly 1800 rpms. An asynchronous motor will spin at a speed lower than the power supply frequency - a symilar asynchronous motor may spin at 1700 rpms.
What is the reasons for the slight decrease in the speed of the motor from no-load to full load?
Without going into the math, the change in speed increases the torque the motor can supply. The further the motor speed and supply speed are apart (known as the slip), the greater the torque will be.
What has to occur for an electric motor to spin freely?
In order for an electric motor to spin freely you will have to make sure you have one thing. You have to have the electric current for the motor to run freely.
What is the advantage by using 8 pole motor instead of 6 pole motor?
The number of poles in a motor will determine the speed of that motor. n=speed, f=frequency, p=# of poles. n=(120f)/p So a 6 pole motor is rated to operate at n=(120*60)/6=1200 rpm. assuming 60Hz frequency Or a 8 pole motor is rated to operate at 900 rpm. Of course due to slip the rotor will always spin slightly slower.
Does a motor spin faster if the armature is winded less?
no. it doesnt...

What changes speed in cars?
What do you mean by that question? There are a lot of things that change speed in a car. When more air and fuel enter the cylinders on a motor, it makes it speed up. When the motor speeds up, it makes the transmission spin faster, and when you shift gears it makes the driveshaft spin faster, along with the gears in the rearend, unless you have a front wheel drive car, then it makes the wheels spin faster. When the motor speeds up, the accessories driven by the belt or belts on the front of the motor spin faster. when the wheels spin faster, the car goes faster.

In what sense dc motor is better than ac motor?
DC motors can spin at a much faster speed and have higher starting torque.
96 maxima 5 speed how can i tell if the transmission is locking or non-locking differential?
Jack up the front of the car, put in nuetral, and spin one wheel. If the opposite wheel spins the same way, you have locking differential.
Is it possible for a planet to have both planetary spin and orbital motion?
All planets spin on their axes as well as orbiting the Sun.
How does a rotocopter spin?
A rotocopter spins by utilizing a motor to rotate the blades around a central axis. The motor powers the rotation of the blades, creating lift and allowing the rotocopter to fly. The pitch of the blades can also be adjusted to control the direction and speed of the spin.
Is it normal for one tire not to spin in snow?
yes if you have an open differential
What is the reasons for the slight decrease in the speed of the motor from no-load to full load?
Without going into the math, the change in speed increases the torque the motor can supply. The further the motor speed and supply speed are apart (known as the slip), the greater the torque will be.
How do you make propellers spin opposite directions?
You can make propellers spin in opposite directions by using a differential thrust system, where one motor spins in the opposite direction of the other. This can be achieved by programming the motors on a drone or aircraft to rotate in opposite directions, resulting in counteracting torques that cause the propellers to spin in opposite directions.
What Quality control must be performed on a centrifuge?
There are two main issues with a centrifuge concerning quality controls. These are the speed of the motor and the smoothness of the spin.
How do auto locking hubs work?
Normally both wheels on a single axel revolve at an identical rate. Vehicles with auto-locking hubs have sensors that monitor the speed of each wheel independently. If a speed differential is detected meaning if one wheel begins to spin faster or slower than the other wheel, a solonoid (switch) is activated releasing the hubs such that they can spin in and lock. Because only one wheel has torque at any time, if there is a differential speed between the 2 wheels, it means that the torque wheel has broken loose.
