How do you calculate the force of a DC motor?
How do you calculate the force of a DC motor?
The direction of the force is determined by the Fleming’s left hand rule as illustrated in Figure 2. The direction of the force generated by the magnetic field is perpendicular to both the direction of the current and the field….DC Motor Calculations—Part 1.

How do you calculate the full load of a DC motor?
Full load current I, I =P. / 1.732 * V Amps.
How do you calculate induced emf?
Calculating the induced EMF Faraday’s law states: Induced EMF is equal to the rate of change of magnetic flux. Magnetic flux = Magnetic field strength x Area = BA. Therefore…Induced EMF = (change in Magnetic Flux Density x Area)/change in Time. Therefore, Induced EMF = (Bπr2n)/t.
What are 3 types of DC motors?
There are three basic types of dc motors: (1) Series motors, (2) shunt motors, and (3) compound motors. They differ largely in the method in which their field and armature coils are connected.
How are DC motors controlled?
DC motor. DC motors were the first type widely used, since they could be powered from existing direct-current lighting power distribution systems. A DC motor’s speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings.
What is the speed of DC motor?
The range of the speed regulation of permanent dc motor is from 10 to 15% . If the range is less than 10% then the motor has poor dc regulation. For compound dc motor the regulation range is 25% and for differential compound motor it is 5%.
What is 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.
