A stepper motor is an electro-mechanical device that actuates a train of step movements of a shaft in response to a train of input pulses. The step movement may be angular or linear. The step movement of the motor is according to the input pulse. The performance of a stepper motor — both in terms of resolution (or step size), speed, and torque — is influenced by construction details, which at the same time may also affect how the motor can be controlled. As a matter of fact, not all stepper motors have the same internal structure (or construction), as there are different rotor and stator configurations. Advantages and Disadvantages of Stepper Motor The advantages of a permanent magnet stepper motor are It is compact and small in size, which makes it useful in many applications Due to the absence of any external excitation, the losses are less Due to the absence of any external excitation, the maintenance is less. It can be connected to the external circuit, to control the speed of the
Generally speaking, high temperature resistant motors are defined by their insulation class. The field of stepper motors usually involves six insulation classes. High temp stepper motors have special requirements for materials due to their use in high temperature situations, including enameled wire, skeleton, magnets, bearings, grease, end caps, etc., especially varnished wire, skeleton and magnets. High temperature motorsfrom oyostepper.com are rated to operate in ambient temperatures between 50 degrees C and -20 degrees C. While this satisfies the majority of uses, there are certain applications that require the motor to operate at higher or lower temperature ranges than what standard motors allow for. Unfortunately, operating standard motors anywhere outside these temperature ranges will result in poor performance. High Temperature Stepper Motor Frame size selection: High Temperature Stepper Motors are typically made in groups or families, the families are identified by the outer d
