Stepper Motor Fundamentals
What is a Stepper Motor?
Astepper motoris a brushless DC electric motor that moves in precise angles, called steps, by converting a series of electrical pulses into rotational motion. They will not produce continuous motion from a continuous input voltage, and it will stay at a particular position as long as the power is "on". Step motors are controlled with the use of discrete electrical pulse signals. Each pulse will rotate the step motor shaft by a fixed angle called a "step". ISL Products can offer stepper motors with several different step angles (0.45°, 0.9°, 1.8°).
If the pulses are carried out in a specified sequence, the motor will spin continuously; the speed can be controlled by the rate at which the pulses are sent. These natural step angles allow a step motor to be accurately positioned without the accumulation of error. The step motor produces output torque from the interaction between the magnetic field in the rotor and in the stator. The magnetic field strength is proportional to the amount of current applied to the windings as well as the amount of turns in the windings.
Stepper motors fill a unique niche in the motor control world. These motors are commonly used in measurement and control applications throughout various industries. Sample applications include Ink Jet Printers, CNC machines, 3D Printers, Automation & Packaging machines, Security & Surveillance systems, Medical Tools & Equipment, Robotics and Vending machines.
Stepper Motor Construction
A stepper motor consists of a permanent magnet sandwiched between the two rotor halves (causing axial polarity), which make up the spinning part of the motor, placed into a stator housing where the stator coils of wire make up the different motor phases. With a 2 phase stepper motor, each phase has four coils. The phase is magnetized where the A and A- phases (or B and B-)are magnetized at the same time, so that both A phases are magnetized as one pole, and both A- phases are magnetized as the opposite pole because the winding direction of the A phase is opposite the winding direction of the A- phase.
The rotor is connected to the motor shaft, which gives the output rotation and torque of the motor when voltage and current pulses are applied to the motor windings. The bearings on either side of the rotor allow for smooth rotation with little friction and wearing. The bearings are placed into their designated spaces in the front and rear endcaps, which allow for concentricity of the rotor inside the stator. Perfect alignment of the rotor and the stator is very important because the airgap between them, where the motor torque is generated, must be equal on all sides and is only a few nanometers wide – thinner than a strand of hair.
Unique Features & Advantages of Stepper Motors
•Brushless – Stepper motors are brushless, which means they have a high reliability with little maintenance. The commutator and brushes of conventional motors are some of the most failure-prone components, and they create electrical arcs that are undesirable or dangerous in some environments.
•Load Independent – Stepper motors will turn at a set speed regardless of load as long as the load does not exceed the torque rating for the motor.
•Open Loop Operation – Stepper motors move in quantified increments or steps. As long as the motor runs within its torque specification, the position of the shaft is known at all times without the need for a feedback mechanism.
•Holding Torque – Stepper motors are able to hold the shaft stationary.
•Excellent response to start-up, stopping and reverse.
•Inherently more fail safe than servo controlled motors.
