What is the relationship between the number of steps and the speed?
There are two modes of operation of four-phase step motor, one and four phase four. Two, four phases eight. To figure out the speed of a four-phase, eight-shot operation, you need to understand two basic concepts first. 1, take count: the number needed to complete the periodic changes in A magnetic field pulses or conducting state expressed with n, or refers to the motor turns A pitch Angle pulse number, four phase motor, for example, there are four phase four operation modes is AB - BC - CD - DA - AB, four phase eight beats operation mode is A - AB - B - BC - C - CD - D - DA - A.
These two concepts clearly, after we again to calculate the rotational speed, with basic steps within 1.8 ° Angle of stepping motor as an example (now in the market of conventional two, four basic steps from the Angle of the hybrid stepping motor is 1.8 °), four phase eight running mode, each receives a pulse signal, around 0.9 °, if receive 400 pulses every second, so speed is 400 megabits per second x0. = 9 ° 360 °, equivalent to turn every second, every minute 60. Other things can be calculated.
Step Angle: corresponding to a pulse signal, the angular displacement of the rotor of the motor is expressed in theta. Theta = 360 degree (the number of rotors), in the case of the normal two and four phases, the rotor teeth are 50 teeth motor. Four run time interval Angle is theta = 360 degrees/(50 * 4) = 1.8 degrees (commonly known as a whole step), eight beats runtime interval Angle is theta = 360 degrees/(50 * 8) = 0.9 degrees (commonly known as half step).
