AC Motor Circuit Diagram

This triac-based 220V AC motor speed controller circuit is designed for controlling the speed of small household motors like drill machines. The speed of the motor can be controlled by changing the setting of P1. The setting of P1 determines the phase of the trigger pulse that fires the triac. The circuit incorporates a self-stabilizing technique that maintains the speed of the motor even when it is loaded.

220VAC Motor Speed Controller Schematic
For example, when the motor of the drill machine is slowed down by the resistance of the drilled object, the counter-EMF of the motor also decreases. This results to a voltage increase in R2-P1 and C3 causing the triac to be triggered earlier and the speed increases accordingly.

If the main use for this circuit is to control the brightness of a light bulb, RS and CS are not necessary.

AC Motors in Ahmedabad

Main Features:

• The Frames of motors are made of Cast Iron with integral feet, thin ribs & larger cooling area.
• End covers are also of cast iron with enough mechanical strangth.
• High Grade electrical Steel lamination are used for stator & Rotor of minimize losses.
• The Stator stack is assembled under pressure & clamped tightly with the help of cleats & then inserted in to cast iron frame.
• The Rotor are dynamically balanced to ensure quite & vibration free operation.
• Modified Ployester super enameled copper wire is used for winding. Double layer concentric winding with optium over hang gives improved performance & high reliability.
• All standard motors are provided with class 'B' insulation. Motors with any other class of insulation ( F' of H' ) can be offered on request.

DC Motors in Ahmedabad

DC or Direct Electric Current Motor works on the principal, when a electric current carrying Conductor is placed in a magnetic field, it experiences a torque and has a tendency to move. If the direction of electric current in the wire is reversed, the direction of rotation also reverses. When magnetic field and electric field interact they produce a mechanical force, and based on that the working principle of dc motor established. 

PMDC Motor in Ahmedabad
The PMDC motor designed by us has high starting torque, permanently lubricated sealed ball bearings and class B insulation. Their DC motors are available in different forms such as standard foot form and flange mounting form that are for solid constructions. Our range of motors comprises of gearboxes, integral tacho, encoder and other accessories. 

Specification of DC MOTORS : DC or Direct Electric Current Motor works on the principal, when a electric current carrying Conductor is placed in a magnetic field, it experiences a torque and has a tendency to move. 

Structurally and construction wise a direct electric current motor is exactly similar to a DC generator, but electrically it is just the opposite. Here we unlike a generator we supply electrical energy to the input port and derive mechanical energy from the output port.
