Turning Motor End Cover Prototypes for Stepper Motor 

The motor end cover is a back cover installed behind the motor and other housing, commonly known as "end cover". It can be manufactured by CNC engraving, sand casting, transparent acrylic(PMMA/PC) 3D Printing. Motor control structure Dc brushless motor is a kind of synchronous motor, that is to say, the speed of the motor rotor is affected by the speed of the motor stator rotating magnetic field and the number of rotor poles (p) : n= 120. f/p. When the number of rotor poles is fixed, the rotating speed of the rotor can be changed by changing the frequency of the stator rotating magnetic field. Dc brushless motor is a synchronous motor coupled with electronic control (driver), control the stator rotating magnetic field frequency and the motor rotor speed back to the control center to repeatedly correct, in order to achieve close to the characteristics of the DC motor. That is to say, the DC brushless motor can still control the motor rotor to maintain a certain speed when…
