Working principle and application scenarios of stepper motor

Foreword Starting from this article, the Zhizhi Classroom series of articles will bid farewell to the relevant knowledge of [Microcontroller Fundamentals] and start the tour of [Stepper Motor]! Please study hard and continue to pay attention~ Stepper motor is one of the common motors in our life. As the name suggests, a stepper motor rotates […]

Ten common faults of three-phase AC servo motor

Three-phase AC servo motors are widely used, but after long-term operation, various failures will occur. It is an important work to prevent the expansion of the fault and ensure the normal operation of the equipment to determine the cause of the fault in time and deal with it accordingly. Motor encoder alarm 1. Cause of […]

The difference between PLC control and relay control

For the star-delta starting circuit, those who are engaged in electrical and industrial control are certainly no strangers. Generally, such circuits are constructed with time relays, intermediate relays and AC contactors. The following figure is the motor star-delta starting control circuit constructed with PLC: Let’s look at its main program: In the above figure, TON […]

Design of BLDC Motor Based on GD32F310 MCU

Power tools are a general term for tools powered by DC or AC motors. As the most important electromechanical energy conversion device, the motor can effectively improve the energy utilization efficiency and achieve the policy goal of energy saving and emission reduction by reducing the energy consumption of the motor. With the policy requirements of […]

How to protect the PLC system from foreign intrusion?

Today, the once sacred boundaries between IT and OT networks are becoming more and more blurred. As one of the most important links in industrial control and industrial control networks, PLCs are increasingly connected to their industrial control systems or other PLCs. device of. So, how can we protect our PLC system from foreign invasion? […]

Detailed explanation of the principle of DC brush motor

Why do power tools (such as hand drills, angle grinders, etc.) generally use brushed motors instead of brushless motors? To understand, this is really unclear in a sentence or two. DC motors are divided into brushed motors and brushless motors. The “brush” mentioned here refers to carbon brushes. What does the carbon brush look like? […]

The basic concept and main transmission parameters of permanent magnet servo motor

The concept of robots is already very broad. This article discusses the servo motors for robot joints required by the industrial automation industry, and does not involve the composite and integrated joint servo motors of service robots. Industrial robots are generally classified into linear robots (also called Cartesian robots), multi-degree-of-freedom robots (also called multi-joint robots), […]
