The World of Electric Motors

The World of Electric Motors 2 Types of Electric Motors Electric motors are categorized into 2 main types depending on how the electrical current is transferred. Alternating Current (AC) motors Direct Current (DC) motors the 1st and earliest effective for systems that are hard to start motors used have a steady and constant current have high starting power built to transmit lower levels of overall commonly used in most electric appliances in the house power incapable of producing power over long period of time the amount of power specified by AC motor is determined by the amount of power needed to operate the system (DC) motors 2 Main Types (AC) motors 2 MainTypes Brushless DC motors Induction Motors rely on a small difference in speed between the stator rotating magnetic field and rotor shaft speed called slip to induce rotor current in the rotor AC winding uses a switch to generate the magnetic drive that powers the rotor have higher cost of construction generally inexpensive and reliable used in automotive, HVAC, computer, electronic, medical industries and industrial applications such as industrial robots and used in almost every procesS especially in water pumps, kitchen applianeces, electric fans, and boiler pumps actuators. Brushed DC motors Synchronous Motors uses rings that conduct the current and form the magnetic drive that powers the rotor. efficient in maintaining the power for the overall sytem used in motorized toys, computer peripherals, appliances, push-button adjustable car seats. generally inexpensive and reliable used where accuracy is important - clocks, timers and metering pumps Generally, the DC and AC motors are easily found everywhere from the home to the car to industrial environment. DC motors and AC motors are different in many ways, but they still both are used to power the world of electric appliances. MROSUPPLY SINCE 1898 www.MROSupply.com
