Between series excited DC motor field winding and rotor winding through the brushes and commutator motors in series price, the excitation current and the armature current is proportional to the stator flux with increasing excitation current increases motor applications, transfer Moments approximately proportional to the square of the armature current, with increasing speed torque or current decreases rapidly. First, the AC induction motor AC induction motor is the leading run AC voltage motors widely used in electric fans, refrigerators, washing machines, air conditioners, hair dryer, vacuum cleaner, hood, dishwasher, electric sewing machines, food processing machines and other household electrical and power tools, small electrical and mechanical equipment. Motor brand, the Swiss mechanical and electrical liter (certified), motor ventilation and air conditioning provided by the liter Swiss mechanical and electrical equipment factory. L Rui HVAC Electrical Equipment Factory (www.dzsrxfkt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In liters Swiss electromechanical leadership with the staff warmly welcome all inquiries negotiations to create liter Swiss electromechanical better future.
