Operation MOONS’ linear stepper motors are available with 2-coil bipolar windings, bipolar windings motors typically have 4 leads. Bipolar motors have a single winding per phase. The current in a winding needs to be reversed in order to reverse a magnetic pole, so the driving circuit must be more complicated, typically with an H-bridge (an H bridge is an electronic […]

Actuators can be classified into two types based on their motion. Two primary actuator types are rotary and linear. Rotary actuators will turn something a number of degrees in a circle – it might be a limited number or an infinite number. Linear actuators, in essence, move something along a straight line, usually back and […]

As a compact linear actuator, linear stepper motors are often used to realize linear motion or linear reciprocating motion. The main principle is through the screws and nuts meshing, adopting some method to prevent screws and nuts relative rotation, to achieve the linear movement of the mechanism. The purpose of this paper is to introduce […]

With the application of servo motors, stepper motors, intelligent motors and ball screws in machine tool and automation, flexible couplings are widely used as a device to transfer torque and protect motors and lead screws. However, most people do not know how to apply the coupling. Cases of unreasonable selection and the incorrect installation often occur, resulting in more and more […]

Linear stepper motors are offered with a variety of lead-screws, which are designated by their lead. Lead is the distance the nut travels when the lead-screw turns one revolution. For a linear stepper motor, larger leads will make the nut move faster, but with less force. To determine the linear travel per step divide the screw […]
