AC/DC gear motors have the advantages of low energy consumption, superior performance, small size, compact structure, reliable and durable, etc.

    According to speed, a motor itself can be divided into low speed (low rpm) motor and high speed (high rpm) motor. According to functions, there are drive motors and control motors. No matter what kind of motor, there is a rated speed and torque. To obtain variable speed, a dedicated controller or speed regulator is needed to control the speed, but this will increase a certain cost and cause the motor price to become higher. On the other hand, performance of the motor after speed regulation will decrease to varying degrees. In this case, gear motor can perfectly solve this problem.

    How does Hall Sensor Work on BLDC Motor?

    Hall sensor can also be called as the Hall encoder. The Hall sensor in the brushless DC motor controller is used to detect the rotation speed of the bldc motor. In some applications, it is necessary to adjust the speed of the brushless DC motor, and to ensure that the bldc motor remains unchanged at a certain speed, so it is necessary to add a Hall sensor that detects the speed for feedback. The brushless DC motor controller will output different control pulse signals according to the detected speed value, and finally achieve the purpose of quickly adjusting the speed of the brushless DC motor.

    Why BLDC Motor Runs with Controller?

    Nowadays, many automation equipment manufacturers have begun to pay attention to brushless DC motors. They want to use brushless DC motors to replace induction motors, stepper motors, etc., which have many defects such as low efficiency, high noise, and high power consumption. Recently, ATO has also received many inquiries from new and old customers: Do BLDC motors and brushed DC motors both rotate when powered? Actually not. Brushless DC motors must be equipped with corresponding controllers to rotate. This is determined by the structural principle of the brushless dc motor.

    What is a Magnetic Stirrer?

    A magnetic stirrer also known as magnetic mixer is a kind of laboratory equipment which is mainly used for stirring or heating stirring in low-viscosity liquid or solid-liquid mixing experiments.

    What is a TDS Meter?

    The TDS meter is a kind of water quality tester, which is a small handheld device used to indicate the total dissolved solids in a solution (usually water). Since dissolved ionized solids (such as salts and minerals) increase the conductivity of the solution, the TDS meter can measure the conductivity of the solution and estimate the TDS value based on the measured value. It should be noted that TDS meter does not measure pollutants. Although TDS meter is often used as a water quality testing instrument, it does not directly tell you whether the water is healthy. In fact, some healthy minerals in the water, such as potassium, magnesium, calcium, etc., can cause the TDS meter to suddenly rise. Therefore, using TDS meter for water filters with mineralizers may have the opposite effect to your expectations. Your water may also contain heavy metals such as lead, or other pollutants such as pesticides, drugs, and hexavalent chromium. TDS meter cannot detect these pollutants.

    What is a Hipot Tester?

    Hipot tester, also called dielectric strength tester, is used to carry out the test of applying a specified AC or DC high voltage between the live part and the non-live part of the electric appliance to check the hipot of the insulating material of the electric appliance. In long-term work, electrical appliances must not only bear the effect of rated working voltage, but also bear the effect of overvoltage that is higher than the rated working voltage for a short time during operation(The overvoltage value may be several times higher than the rated working voltage value). Under the action of these voltages, the internal structure of electrical insulating materials will change. When the overvoltage intensity reaches a certain value, it will cause the insulation breakdown of the material. The electrical appliances will not operate normally, and the operator may get an electric shock, endangering personal safety. The main electrical safety test indicators include AC/DC hipot, insulation resistance, leakage current, ground resistance, etc. AC/DC hipot tester is used to test the electrical safety performance of the product under actual working conditions, so it is one of the important instruments for testing the electrical safety performance of the equipment.
