What is the power of stepper motor?
Stepper motors have a rated voltage and current. A typical stepper motor like our NEMA 17 might have a rated voltage of 2.8 Volts and a maximum current of 1.68 Amps. This basically means if you hook it up to 2.8 Volts it will draw 1.68 Amps.
How do stepper motors work?
The stepper motor converts a pulsing electrical current, controlled by a stepper motor driver, into precise one-step movements of this gear-like toothed component around a central shaft. Each of these stepper motor pulses moves the rotor through one precise and fixed increment of a full turn.
How is the power of a stepper motor defined?
Stepper motor power is defined by both speed and the inertia of the load. Remember that if you are driving a stepper motor at a low speed, you are accelerating the load from a dead stop to the next step, then decelerating the motor to a stop.
How does a stepper motor work on a gecko?
Below a certain speed, called the corner speed, the current would rise above the motor’s rated current, ultimately to destructive levels as the motor’s speed is reduced further. This can be seen in Figure 1. To prevent this, the drive must be set to limit the motor current to its rated value.
What kind of driver do you need for a 2 phase stepper?
The driver you specify is for a 2 Phase stepper with a maximum of 4.5 A per phase capability. The first thing to understand is that 2 phase and 3 phase stepper motors do not act like AC motors at all. Look at the torque characteristics you posted in the question.
How does microstepping affect the power of a motor?
Microstepping might be a little less efficient, but with smart controllers it is probably not much, and it will definitely “smooth out” vibration when running. Running at a lower current should reduce the power per controller, and the power draw when stalled is about the same as max load, with the caveat that things are getting heated.
