Step 1, from the Angle of stepper motor, stepper motor stator winding of each change current state, the Angle of the rotor turning said interval Angle. Rotor, the more the number of steps away from the smaller Angle of stator phase number, the more the more step away from the smaller the Angle of the tempo of way to power, step away from the Angle of the smaller type: in the stator phase number m - Z - rotor teeth C - modes: C = 1 single phase electricity in turn, bipolar modes in turn C = 2 modes in turn single or double phase 2, the related conclusion (1), the control input to the number of pulse stepper motor can control the angular displacement of stepper motor; Diction, control input to the pulse frequency of the stepper motor can control the step motor speed; (3), the control of step motor stator winding current order can control the stepper motor rotation direction. 3, the relationship between torque and rotational speed speed formula: n = 60 f/P (Speed, f = power frequency, n = P = pole logarithmic)Torque: rotational torque mechanical element, known as the rotational torque, torque for short. Mechanical components under the action of torque will produce a certain degree of torsion deformation, so the torque is sometimes called a torque. Torque formula: T = 9550 p/nT is torque, unit N· MP is the output power, the unit KWn is the motor speed, unit of r/min specific relationship is derived as follows: 1)Power = force * speed: P = F * V formula 12)Torque (T)= torsion (F)* action radius (R)Namely: T = F * R by type, can launch F = T/R formula 23)Linear velocity (V)= 2πR * speed per second (N seconds)= 2πEach speed (R *N)/ 60 =πR * n / 30 formula 3 will formula 2, 3 in formula 1: aP = F * V = (T/R )* (πR * n / 30)= (π/ 30)W * T * P = n points of power units, T = Nm torque unit, unit of n points = RPM RPM if P unit for KW, so is the following formula: P * 1000 = & PI; /30*T*n 30000/π* P = T * n30000/3。 1415926*P=T*n9549. 297 * P = T * n
