Model No.20BY25-007

20BY25-007 Permanent Magnet Stepper Motor is a type of Permanent magnet stepper motor and also belongs to Stepper Motor.
Permanent magnet stepper motors use a permanent magnet (PM) in the rotor and operate on the attraction or repulsion between the rotor PM and the stator electromagnets.

MAINTEX's PM stepper motors are widely applied in many innovative applications, including: computer equipment, photographic systems, optoelectronic devices, valve control, ATM equipment, CNC machine, automatic winding machines, electronic clocks and medical equipment, etc.

How to distinguish Dc motor, AC motor, stepper motor and servo motor from the definition

DC motors, AC motors, stepper motors, and servo motors can be distinguished by definition:

1. What is a DC motor?
Answer: A rotating motor whose output or input is DC power is called a DC motor.

2. What is an AC motor
Answer: A rotating motor whose output or input is AC electric energy is called an AC motor.

3. What is a stepper motor
Answer: It is an actuator that converts electrical pulses into angular displacement. In layman's terms: When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (ie step angle) in the set direction. You can control the angular displacement by controlling the number of pulses, so as to achieve accurate positioning; at the same time, you can control the speed and acceleration of the motor rotation by controlling the pulse frequency, so as to achieve the purpose of speed regulation. There are three types of stepping motors: permanent magnet stepping motors (PM), reactive stepping motors (VR) and hybrid stepping motors (HB). Permanent magnet stepping motors are generally two-phase, with small torque and volume, and the step angle is generally 7.5 degrees or 15 degrees; reactive stepping motors are generally three-phase, which can achieve large torque output, and the step angle is general It is 1.5 degrees, but the noise and vibration are very large, and it has been eliminated in the 1980s in developed countries such as Europe and the United States; hybrid stepping motor refers to the advantages of mixing the permanent magnet type and the reactive type, and it is divided into two-phase and five-phase : The two-phase stepping angle is generally 1.8 degrees and the five-phase stepping angle is generally 0.72 degrees. This kind of stepping motor is the most widely used.

4. What is a servo motor
Answer: The servo motor is also called the executive motor. In the automatic control system, it is used as an actuator to convert the received electrical signal into the angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main feature is that there is no rotation when the signal voltage is zero, and the speed decreases at a uniform speed as the torque increases.
