When you are developing a stepper motor controller, do you often face the following confusions: how to select field effect transistors for the stepper motor driver? Are there good domestic MOS tube alternatives available on the current market? Will the wrong choice result in poor quality products? If you have these concerns, don't worry, Feihong Semiconductor will provide answers and high-quality products for you.

Firstly, understand the basic knowledge of stepper motors and their drivers.

What is a stepper motor?

A stepper motor is an electric motor that converts electrical pulse signals into corresponding angular or linear displacement. For every input pulse signal, the rotor rotates by a certain angle or moves forward one step. The output angular or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. Therefore, a stepper motor is also called a pulse motor. It can be classified into reactive, permanent magnet, and hybrid types based on the rotor, each with its unique advantages and disadvantages.

What is a stepper motor driver?

A stepper motor driver is a power amplifier that drives the stepper motor to operate. It receives control signals from the controller (such as PLC or microcontroller) and controls the stepper motor to rotate by a corresponding angle or number of steps. The driver mainly consists of two parts: the ring distributor and the power amplifier. The MOS transistor is usually in an H-bridge structure (four MOS or double the quantity), ensuring the effective operation of the stepper motor.

Secondly, the pain points in selecting stepper motor drivers.

In the process of developing a stepper motor controller, you may encounter the following pain points:

Uncertainty about how to select the model: There are many options on the market, from reactive, permanent magnet to hybrid motors, choosing the right driver can be headache-inducing.

Worrying about the quality of domestic alternatives: Most researchers are accustomed to choosing imported field effect transistors (MOS tubes), even if they are expensive, they dare not easily try domestic alternatives.

Fear of selecting poor quality products: In fierce market competition, a minor error in selection can lead to project failure and increased costs.
