Stepper motor speed and the frequency calculation formula of


stepper motor speed can be controlled with frequency, is directly proportional to the frequency and speed of the stepper motor, can pass calculation formula, calculates the stepper motor's speed.
stepper motor speed = frequency * 60 / ((360 / T)* x)
the speed of the stepper motor unit is: RPM
frequency unit is:
x Hertz real refers to multiple segment
T: inherent stepper Angle

for example:
step motor using the whole step, namely 1 segment; Frequency of 1 k, namely 1000 hz; To paraphrase formula: 1000 * 60/200 = 300 RPM
note: this formula suitable for two phase stepper motor.

highest stepper motor no-load speed what is the real meaning of
two phase stepper motor no-load speed of up to more than 2000 r/min, but it is just a reference, no practical significance, because of the stepper motor torque with the increase of rotational speed decreased rapidly, the high speed to a certain degree of torque is almost zero. Stepper motor step in the whole (without segmentationEvery one revolution of the 200 pulse)Improve the clock frequency, people often find motor when far from reaching the highest speed of light is blocked in turn, that confuse the highest speed how much, or even doubt whether your system is normal, that is the real reason.
the operation of the stepping motor under low speed performance is of practical significance, is generally 300 RPM to 600 RPM, considering the users to use mechanical reduction gear load, provide enough to make motor torque, constant speed of the motor is often choose in dozens of RPM, the motor for his great strength, high efficiency, low noise, vibration problem, want to rely on to increase the segmentation method to solve the of the driver.
formula for calculating the maximum no-load speed:
no-load speed (Revolutions per minute)= 60 times the clock frequency / 200 times the fine fraction (M is fine)
if M = 16, clock frequency = 150 KHZ
the highest no-load speed is equal to about 2800 RPM
60 times 150000, divided by 200 and 16, the product of the results.
