Hand-held power tools

Permanent magnet synchronous motor (PMSM) is widely used due to its advantages such as high efficiency, small size, simple structure and fast dynamic response.  For the application of power tools, the overall scheme adopts intelligent power controller (SPC5L18A)+ power MOS(SVT042R5NL).  The high speed holeless comparator algorithm is used for motor control, and the cost of electronic control is reduced by the Holeless scheme. At the same time, it has the advantages of small volume, large power and so on.

SPC5L18A is a high-performance controller developed specifically for motor control and CNC power control. It uses a single cycle 52 kernel, embedded 16K byte Flash memory, 256 byte internal data memory and 1K byte external data memory. It integrates six NMOS Pre-driver, two LDOs, two high-speed operational amplifiers, four comparators, high-speed ADC and multiplication and division unit (MDU). At the same time, the built-in 16MHz high-precision oscillator, multiple general timers, UART, SPI and special timer T6L for motor control so that users can design such systems with maximum flexibility and minimum overall cost.

Topology

The overall scheme topology of hand-held power tools is as follows:
