Does the stepping motor start a lot?
To look at the power, here is an algorithm for the motor to start the current: Motor starting current impact, and the nature of the load (constant torque and constant power, fan class) and start the way (direct start, since the lotus root step-down start, star triangle, triangle of yanbian, the frequency-sensitive variable resistance and frequency). Typically, the 38/3 ac asynchronous motor is used as an example for the star delta, which can be estimated: The 110KW motor, which is rated at approximately 200A (also can be estimated at 2 times power), At direct start-up, the current is estimated at 6 times the current rating, about 1200A.
When the star delta starts, the starting current is one third of the time when it is launched directly, and 400 a. (ac asynchronous motor, common 75KW, 90KW, 110KW, no one has ever seen 100KW, with 110KW for example, and other power for this type of push)
Look at the multi-power step motor, pulse drive, 5V voltage, some under 200mA
