NEMA17 0.48N.m 2 phase hybrid bipolar stepper motor with encoder 1.8 stepping motor for medical system

Ti What is stepper motor?

• Stepper motor is an actuator transforming electric pulse into angular displacement. Popularly, when receiving a pulse signal, the stepper motor will rotate a fixed angle (namely ''stepping angle'') according to the direction set for the stepper motor. The angular displacement volume can be controlled by controlling the pulse number to achieve the purpose of positioning accurately. In the meantime, the rotational velocity and acceleration of motor can be controlled by controlling the pulse frequency to achieve the purpose of speed control.

Working principle of stepper motor

• To make the motor shaft turn, first one electromagnet is given power, which makes the gear’s teeth magnetically attracted to the electromagnet’s teeth. The point when the gear’s teeth are thus aligned to the first electromagnet, they are slightly offset from the next electromagnet. So when the next electromagnet is turned ON and the first is turned OFF, the gear rotates slightly to align with the next one and from there the process is repeated. Each of those slight rotations is called a step, with an integer number of steps making a full rotation. In that way, the motor can be turned by a precise. Stepper motor doesn’t rotate continuously, they rotate in steps. There are 4 coils with a 90o angle between each other fixed on the stator. The stepper motor connections are determined by the way the coils are interconnected. In a stepper motor, the coils are not connected. The motor has a 90o rotation step with the coils being energized in a cyclic order, determining the shaft rotation direction. The working of this motor is shown by operating the switch. The coils are activated in series in 1-sec intervals. The shaft rotates 90o each time the next coil is activated. Its low-speed torque will vary directly with current.

Product description of 1.8 stepping motor

• Accurate Speed Control

The rotational speed of the stepping motor can be precisely controlled ,By controlling the frequency of the electric pulse.

• Automatic machine operation, stable automatic work, high processing efficiency.
