FT8215, GC4931F/S, XM2618 chip, etc.
Its DC brushless motors can be adapted to a variety of applications from air conditioning fan motors to PC cooling fans. 2, reduce the number of external components, reduce the cost because it is equipped with analog voltage comparator, CR oscillation circuit, voltage detection circuit, monitoring timer circuit, no need to add external oscillator, reset IC, help to reduce system costs.
Electric vehicle DC brushless motor controller used M333033, MC33035 and so on, in addition to some is the use of MCU control such as ADynamic tracking. This technology is especially reflected in the three-phase asynchronous motor economizer, which is composed of international advanced microprocessor chip (CPU), thyristor and integrated dual thyristor and other components to ensure the high-end configuration of the equipment.
2, the phase-controlled motor economizer adopts integrated circuit chip control technology, (technology 5 improvement) by microprocessor chip (CPU), thyristor, integrated dual thyristor and other imported components.
3, the use of phase control technology of the motor economizer, is the use of the latest integrated circuit chip control technology with IC chip technology, constantly detect electricityThe motor operates efficiently, thereby changing the input voltage and current. When the motor is detected to change from no-load to light load to full load, keep the motor constant speed unchanged.
4, now the so-called energy-saving appliances, many are actually "stealing electricity" devices, including letting the meter stop, reverse, how can. The design principle of this kind of product is based on power electronics, using the latest integrated chip control technology, by monitoring the phase difference of the current and voltage of the AC motor to dynamically adjust the energy supply to the motor, so that the motor always works in the best efficiency state, and achieve "intelligence" between the motor and the power gridThe "energy management function".
5, phase-controlled power saving technology adopts the improvement of the external operating environment of the motor to achieve dynamic power management, which is one of the two mainstream power saving technologies of the AC motor complementary to the inverter. Phase-controlled motor economizer adopts integrated circuit chip control technology, which is composed of microprocessor chip (CPU), thyristor, integrated dual thyristor and other imported components.

2, TDA5142T is a position sensorless brushless DC motor special control chip produced by Philips. The chip contains a starting circuit, a full wave commutation circuit and a protection circuit, which can easily realize the starting and control of position sensorless brushless DC motor. MP6403 is a high power inverter bridge module produced by Toshiba Corporation, which is specially used for driving three-phase motors and bipolar pulse motors, with a maximum rated drain current ID = ±5A [1].
3, there are more types of driver chips on the market, if it is a drive coreChip and MCU integrated driver There are several chip manufacturers have similar products, you can find ON (8824) and Allgro these two, there are drivers that meet your application requirements. If some complex control functions are needed, the special chip may not be able to meet the requirements, and the single chip microcomputer is needed for product design.
The hard disk motor needs to be driven by a special driver chip. In line chip can be LB11983 or TDA5145, the patchThe DRV10983, DRV11873 and TB6588FG are available. The motor that needs to drive the hard disk is immovable with ordinary direct current, it uses four pulse currents, and it has to be programmed to drive it with a combination of hardware and software.
The hard disk motor is a brushless motor, not a stepper motor. And the detection relies on the back potential. For simplicity, you can use a dedicated driver chip, such as the TDA5140A.
Hard disk disk spindle motor is a brushless motor, need to be driven by a special driver chip, the driver chip signal source is fromThe main control chip is obtained. Note: Different manufacturers of spindle motor, the need for the driver chip is different.
The hard disk motor needs to be driven by a special driver chip. The in-line chip can be LB11983 (the power supply cannot exceed 6v when connected to the hard drive motor) or TDA5145, and the patch can be selected DRV10983, DRV11873 and TB6588FG. The multi-independent head scheme itself has many different application purposes and corresponding implementation methods. Different methods of implementation have different difficulties. Each independent head has a completely independent complete sub-hard driveThe control circuit.
