The three-phase reactor to be like and its external structure, that is, there are three core column and of three winding, three windings into a star, and through the slip ring and brush with three-phase wound rotor motor rotor winding. Initially started when the wound rotor motor, www.dongfeng-motor.com motor speed is very low, so the rotor frequency f2 is a large (close to f1), in the core loss is very big, the equivalent resistance Rm is very big, therefore, limit the single phase induction motor starting current, increase the starting torque. Current frequency decrease with the increase of n, rotor (f2 = s f1) Rm decreases, and keep the starting current and torque must be numerical. Frequency-sensitive rheostat is actually using the rotor frequency f2 smooth change for the purpose of the smooth rotor loop total auto spare parts resistance decrease. After the start, the rotor winding short sub, the frequency- sensitive rheostat removed from the circuit. Because of frequency-sensitive rheostat equivalent resistance Rm and reactance Xm varies with the frequency of rotor current, responsive, so called frequency-sensitive rheostat. Advantage: the structure is simple, low cost, easy maintenance, smooth start. Weakness: the inductance exists, cos Φ low starting torque is not large, suitable for wound rotor motor start light load.
According to the role of it in line and its installation position in the complete sets of power distribution equipment to determine the structure of it. Only used to single phase motor isolate the power supply, simply 3 phase induction motor choose products with no arcing cover; Such as used for breaking load, it should be chosen with arcing cover, and it is through the lever to manipulate the product; Such as the central can't handle knife switch to cut off the load current, the other can be cut off water pump price in the form of a certain load current, but it must be chosen with arcing cover of the knife switch. rotor and stator In addition, still should root tree is positive or side operation, is a direct manipulation www.facebook.com/dongfeng.motor or lever transmission, is the connection or the plate in front of the plate to choose structure. HD11, HS11 for magnetic stand, don't cut off the circuit with a load, only for current isolation.
