Dc servo motor controller, it includes stator and the rotor iron core, winding commutator rotor motor controller, servo motor controller, servo motor controller winding, winding speed motor controller, controller speed motor commutator, described the rotor iron core by an laminations of overlying fixed on the rotor motor controller. Dc servo motor controller is divided into a brush and brushless motor controller. A brushless dc servo motor controller - — Motor controller of low cost, simple structure, big start torque, wide speed range, easy control, need to be maintained, but the maintenance is convenient, In carbon brush) , will produce electromagnetic interference, have on the environment. So it can be used in ordinary industrial and civil occasions is sensitive to the cost. Brushless dc servo motor controller - — Motor controller is small in size, light weight, the output is big, fast response, high speed, small inertia, the rotation smooth, stable torque. Easy to implement intelligent and flexible its electronic commutation, can square wave or sine wave phase commutation. There is no loss of carbon brush and maintenance-free motor controller, high efficiency, low operating temperature low noise, electromagnetic radiation is very small, long life, can be used for all kinds of environment. There are two kinds of situation makes the motor controller movement in the braking state: 1, the motor controller is in a state of slow: the speed of the motor controller decline is the result of the armature voltage decreases. But when the voltage is suddenly hours, moment of inertia of the motor controller makes the speed cannot mutation, and also the potential e not mutation. This will be the possibility of Ua is less than e, made the current flow to produce braking torque. 2, motor controller has the vertical load and load downward movement: when the servo motor controller must generate with the movement in the opposite direction of brake torque balance weight falling heavy torque. Under braking condition, from the kinetic energy of the rotary motor controller and heavy objects fall when the potential energy is converted to electric current in the form of feedback to the power supply, this way of brake is often referred to as regenerative braking.
