DESIGN OF 1 KW DC MOTOR Harsh Saini , Abhinav Bhatia, , Hemant Kr. Soni, Himanshu Sharma Student, Electrical Engineering, Poornima College Of Engineering, Rajasthan, India Student, Electrical Engineering, Poornima College Of Engineering, Rajasthan, India Student, Electrical Engineering, Poornima College Of Engineering, Rajasthan, India Student, Electrical Engineering, Poornima College Of Engineering, Rajasthan, India ---------------------------------------------------------------------***--------------------------------------------------------------------Abstract: The theoretical knowledge about the motor deigning is not enough to construct the motor in practical world. This paper consists the full process to design the 1 KW dc motor. In this paper the design of a 1KW dc motor with its all specific parts are done. What consists stator part like yoke, pole shoe, pole core, brushes, commutator, field winding etc. The design of rotating part like armature, armature winding, no of slots in armature windings are also explained in this paper for 1 KW dc motor. It also includes specific parameters used for designing 1KW dc motor like stator length, no of poles, no of turns in field winding. Copper Material with its mechanical strength is explained for making the field winding and armature winding. The cast iron is used as the protecting material for motor. Output questions like maximum speed of motor, torque generated for the motor are also calculated on the basis of these parameters.
Fig-1: 1 KW DC motor Brushed motors remain to be used for electrical propulsion, cranes, paper machines and steel rolling mills. Since the brushes wear down and need replacement. The dc motors are also used in Lathes machine, Drills, Boring mills, Shaper, Revolving and weaving machines etc.
Keywords: Stator, rotor, commutator, pole, field windings, armature windings
1. INTRODUCTION A DC motor is an internally commutated electric motor designed to be run from a direct current power source. Brushed motors were the first commercially significant application of electric power to pouring mechanical energy and DC distribution systems were used for more than 100 years to work motors in commercial and manufacturing buildings. Brushed DC motors can be different in speed by changing the operating voltage or the strength of the magnetic field. Depending on the connections of the field to the power supply, the speed and torque characteristics of a brushed motor can be different to provide steady speed or speed inversely proportional to the mechanical load.
