Brushless dc motor controller is composed of main body of the motor and drive, it is a kind of synchronous motor controller, rotor speed of the motor controller that is motor controller speed rotating magnetic field of the stator and rotor pole (P)Must have all main parameters of the device controller, is not very understanding, to explain in detail the following contents will. 1, the input voltage: single phase or three phase ac 220 v ac 380 v + 10%; 2, the output field current: 2 a, 5 a (10A 20A…）; 3, locked-rotor current setting value: 1. 3 times the rated current; 4, the rated output current: the armature of 25 a, 50 a; More than 5, it can realize analog signal input, motor controller, coupling with PLC; 6, the output voltage: dc armature 0 -110 v or 0220 v or 440 v, excitation 110 v or 198 v; 7, speed range: 1:30. Knowledge expansion: differential control of the brushless dc motor controller: when the system is to overcome the error and its change always lags behind that of the error change, there is a big inertia system component or (And)There are lag component. Differential is the trend of prediction error change in order to function in advance to avoid being accused of serious overshoot.
