Position feedback for brushless DC motor Since the birth of brushless DC motor, Hall effect sensor has been the main force of realizing commutation feedback.Since three-phase control requires only three sensors and has a low unit cost, they are often the most economical choice for reversing from ...

Reverse direction of BLDC motor Before diving into the BLDC motor feedback options, it’s important to understand why you need them. BLDC motors can be configured for single phase, two phase and three phase;The most common configuration is three-phase.The number of phases matches the number ...

Carbon brush problem solutions for carbon brush motor Brushed DC motor and Brushed AC motor is driven by the carbon brush and commutator pole contact to continue to rotate, so the brush and commutator pole friction is inevitable, also because of the continuous sliding friction, some faint spark i...

Why are micro brushless DC motors & micro brushed DC motors so easy to control? In the application of motor, micro brushless DC motors & micro brushed DC motors are very easy to control, why so? Compared with AC motors, micro DC brushless motors &  micro DC brushed motors are powered ...

Toshiba launches 5A 2-channel H-bridge motor drive IC for on-board applications December 10, 2020 — Toshiba Electronic Components and Storage Devices Corporation (” Toshiba “) today announced the launch of two BRUSh-driven DC motor drive IC “TB9054FTG” and “TB9...

Application prospect of brushless DC motor Permanent magnet brushless motor is a closed-loop mechatronics system, which uses the rotor pole position signal as the signal of electronic switch circuit. Therefore, accurate detection of the rotor position and timely switching of power devices accordi...

What is the characteristic of brushless DC motor for micro vacuum pump? Main Features of brushless DC motor for micro vacuum pump : 1. The suction end and the discharge end can bear a large load (that is, a large resistance), even if the blockage is normal, it will not be damaged. 2, no oil, no p...

What are the advantages of using a meat probe thermometer? 1. There is no need to repeatedly confirm food ripeness When you roast a meat, you often pull it out on the way, poke it to see how tender it is, or cut it to see if the meat is cooked, but this is not only troublesome, frequent alternati...

Effect of oven meat thermometer probe Assuming the grilled steak is 3-4cm thick, the difference between the surface temperature and the center temperature is huge, and the “inconsistency” of the food is difficult for most people to judge at a glance whether the food is ripe enough or ...

What’s function of oven meat probe?   1. What is a food probe or oven meat thermometer probe ? A food probe is a temperature sensor, similar to a thermometer, that is inserted directly into the center of the food. Food Probe technology is derived from foreign countries, and its name is...

What skills should be mastered for CNC aluminum machining parts？ Precision CNC aluminum parts and products are popular because of their light weight and delicate appearance. They are more and more widely used in industry and daily necessities.CNC machining of aluminum alloy is one of the best ma...
