3, as people living standard rise, electric rice fort, microwave oven, air conditioner, electric kettle, electric spot squirrel cage induction motor chung person households, household electricity load is growing rapidly, 1 kw of power load is not enough, so DBJ08-20-94 household electricity load design power of 4 kw, watt-hour meter to choose 5 (20) A. Price increase of residents' income and household electrical appliances, make electric motor parts a home acmotor2.blogspot.com two air conditioners, color TV sets and squirrel cage induction motor computers in the home is not new, has prompted a surge in household electricity load again, therefore DBJ08-20-98 household small diesel engine electricity load design power increased generator to 4-8 kw by 4 kw. The Induction motor high standards had permanent magnet generator been designed by 6 kw, high standards of commercial electric generator housing and more than 130 m2 residence designed by 8 kw, watt-hour meter ac motors are all made of 10 (40) A single-phase watt-hour meter.

Dc braking principle

Dc braking principle. When asynchronous motor stator winding zhongtong into direct current, the magnetic field generated by the constant magnetic field will be the space www.facebook.com/guohong.trading position unchanged, and the speed of the rotor because of its inertia continues with its original spin, at this point, the rotation of the rotor cutting the static magnetic field and produce brake torque, system stored kinetic energy is ac motor converted into electrical energy consumption in the rotor circuit of the motor, thus to achieve the effect of fast brake motor. In order to guarantee the safety of the motor, dc brake is best used with braking energy. Inverter dc brake setting, dc fan motor brake basically set the following three contents 2.1, started to dc brake starting frequency 2.2, applied to the stator winding voltage dc brake. As a result of the stator winding dc resistance is very small, so lamination the dc brake voltage adjusting range is usually the circuit dc voltage of the 0 ~ 10%; 2.3, the braking time. Braking time impossible and actual braking time coincide, in order to ensure the braking effect, usually set slightly larger;
