Choosing the correct BLDC motor is not simply a matter of matching voltage and rated power; for industrial automation, robotics, pumps, electric mobility, solar tracking, lawn equipment, and other motion-control applications, the motor must be selected as part of a complete electromechanical system in which torque, speed, acceleration, thermal behavior, controller compatibility, mechanical installation, feedback,

The main challenges when using a BLDC motor in medical devices are electromagnetic compatibility (EMC), acoustic noise and vibration, thermal management, precise speed and torque control, long-term reliability, sterilization compatibility, and material safety. Unlike general industrial equipment, a medical device must maintain its required function under defined electrical, mechanical, thermal, and environmental conditions, so selecting

A BLDC motor driver circuit converts DC electrical power into controlled three-phase current for a brushless DC motor by coordinating rotor-position detection, electronic commutation, PWM voltage control, current regulation, and power-switch protection. In a conventional six-step BLDC system, three Hall sensors identify the rotor’s electrical position, a microcontroller or motor-control IC interprets the Hall pattern,

A magnetic gear pump uses a magnetic coupling to transmit motor torque through a stationary containment barrier, eliminating the rotating shaft seal, while a traditional gear pump normally transfers torque through a mechanical shaft and therefore requires a dynamic seal or other shaft-sealing arrangement. The pumping principle remains fundamentally similar: meshing gears create expanding cavities

The main principle behind a Magnetic Gear Pump is the combination of positive-displacement gear pumping and non-contact magnetic torque transmission. Instead of using a conventional shaft seal to connect the motor to the pumping gears, permanent magnets transfer torque through a sealed containment barrier. As the gears rotate, they create expanding cavities at the inlet
