24V Handheld Vacuum Cleaner Solution Based on TMI82312

TMI82312 is a dual-core processor that integrates motor FOC control core and 51 cores, 3-way 100V N+N MOS transistor driver and 5V LDO. The hardware motor control module is based on sliding mode observer FOC field-oriented control, the user only needs to It is enough to configure basic parameters, and it is not necessary to spend time on code development at the motor control level. The system control 51 core, which is completely open to users, is equipped with multiple control program sub-modules, which can easily realize constant speed and constant power control, and the motor has good fitting properties, and it is easy to realize the low noise and low jitter operation of different specifications and models.

Due to the advantages of convenient movement, strong suction, convenient charging, stylish appearance and powerful functions, hand-held vacuum cleaners are increasingly favored by the market and are rapidly replacing the earlier “corded” vacuum cleaners. The brushless DC motor (BLDC) is the core component of the hand-held vacuum cleaner, which directly determines the key user experience such as the noise of the whole machine and product life. It has the following advantages:

① Low noise and stable operation
② Small size, light weight and high power density
③ High reliability and long life
④ High speed, high suction, good cleaning effect

In response to this rapidly developing application of small household appliances, Tormicro has launched a 24V handheld vacuum cleaner solution based on TMI82312. This solution is a 24V three-phase non-inductive reference design board controlled by sine wave FOC, using the latest TMI82312 single-chip controller.
