The requirement of precise control in servo applications used in the digital systems led to the development of stepper motors. The precise and zero backlash operation of steppers extended its reach to various position control applications. The lack of requirement of sensors for position control applications was one of the main reasons for preferring stepper motors. Since the stepper motors were...

Permanent Magnet (PM) stepper motors are widely used in accurate systems which are affected by external disturbances and parameters uncertainty. Also, an appropriate nonlinear controller is needed when the problem is to track the reference signal. In this paper, a robust adaptive controller is presented to control rotor angular position in stepper motors. The main idea to make a robust controll...

On the basis of predecessors' research and the existing theory, for convenient and reliable to study the biological effect of low frequency rotating magnetic field, design a high precision and low frequency rotating magnetic field generator, which could be used to stimulate the small area. Choose stepper motor to drive permanent magnet for produce a rotating magnetic field, which can reduce the...

Figure 1. Pull-out torque and output power for a 57 mm PM stepper driven by a unipolar L/R-driver and a NJM3770A bipolar constant current driver. Stepper motors are used in many different types of applications this makes it difficult to recommend a general step-by-step design flow chart. The design process is more an iterative process, involving experience, calculation and experimentation. The ...

This paper presents the design concept of a new spherical stepper robotic wrist motor capable of three degrees of freedom (DOF) motion in a single joint. The spherical wrist motor has significant potential applications where the demands on wrist torque and workspace are low but high speed manipulation of end-effector orientation is required continuously in all directions. Typical applications a...

The modeling and simulation of the electromechanical behaviour of stepper motors are of high interest because they are often used for space application. A commercially available multibody dynamic simulation software, which sets up the equations of motion and the transfer function of the motor and solves them numerically, was used. The results show, that both the dynamic simulation software and ...

To successfully follow a velocity profile, a motor and drive combination must generate enough torque to: accelerate the load inertia at the desired rates, and drive the load torque at the desired speeds. While the size of a bipolar stepper motor generally dictates the low speed torque, the ability of the drive electronics to force current through the windings of the motor dictates the high spee...
