Advantages and Disadvantages of Permanent Magnet Stepper Motor

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...

High Temperature Stepper Motor Frame size selection

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...

The Advantages and Disadvantages of Servo Motor

 The servo motor is an electric motor that allows continuous determination of exact positions, speeds, and torque using control electronics (servo controller). The software interface allows for precise parameterization and programming of the motor's actuation, giving it dynamism as well as individuality. Although servo motors can be small and powerful, they are essential for precise positioning control applications. A signal (data), also known as a pulse width modulator (PWM), controls the servo motor. These are some of the most common servomotor applications. Construction of Servo Motor This motor is a closed-loop mechanism that incorporates positional feedback in order to control the rotational or linear speed and position. This motor is actually an assembly of four things: Normal DC motor- That is in charge of generating the motion through its shaft. Gear reduction unit/gear box Potentiometer Control circuit; Advantages of Servo Motor If a heavy load plac...
