1, FT8215, GC4931F/S, XM2618 chip, etc.
2, CS2018The internal integration of Hall voltage generator, differential amplifier, Schmidt flip-flop and open-collector output stage, etc., it can directly drive low-power motor windings, and only 4 pins, such as optical drive to BA6849, and BA5954 and so on.
3, the current more suitable chip I found IR2110/IR2103, these two are similar, and MC3303MC3303LMD18200.
4, if it is the driver chip and MCU integration of the driver there are several chip manufacturers have similar products, you can find ON beauty (8824) Two companies, Allgro, have driver chips that meet the requirements of your application. 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.
5, cheap DC brush driver chip can be considered L29L298, or Toshiba, Sanyo, or other manufacturers. Just do a quick Internet search. According to their own working current, voltage to choose, but also consider whether the need for reversing, braking and other functions.
1, of course, the stepper motor driver is used to drive the stepper motor, there are several ports on the driver board, as long as you are connected according to the instructions, you only need to input a certain frequency PWM wave to the driver board through the DSP PWM module, and then the drive is completed by the driver board itself, and there are subdivisions on the driver board for you to choose.
2, the control is relatively simple, the working current and voltage can be larger, but the control parameters are generally fixed, the application is not flexible; Using DSP to realize full digital control, the control is more complicatedHowever, the control algorithm is flexible and can automatically adjust the control parameters of different motors.
3, support pipeline operation, so that operations such as taking fingers, decoding and execution can be overlapped. Compared with general purpose microprocessors, other general functions of DSP chips are relatively weak.
4, according to the Cl86D instruction manual, CL86D has oscilloscope monitoring function, the current is set within 0-8A.
5, the biggest difference between DSP and 51 is that it is fast in digital arithmetic, DSP is specially used to quickly calculate digital signals. If you need to make a machineCan the L298N Stepper motor drive module drive the DC motor '> Can the L298N Stepper motor drive module drive the DC motor
Absolutely, the main features of L298N are: high operating voltage, the highest operating voltage up to 46V; The output current is large, the instantaneous peak current can reach 3A, and the continuous working current is 2A; Rated power 25W.
L298N drive module with high voltage, high current output capability, can directly drive the motor, but also through the PWM signal to control the speed of the motor. In the L298N driver module, by changing the outputThe incoming logic level can control the voltage polarity at the output end, thereby changing the direction of the motor.
Equivalent to the L298N can drive two DC motors or one stepper motor. The role of the optocoupler is to isolate the signal, so that once there is a problem on the L298N side, it will not immediately feedback to the MCU and burn the MCU.
L298 motor drive module generally can only drive a small current DC motor, if the circuit diagram is connected correctly should also be able to drive. Together I made a drive module with the diode IN5819, the optocoupler with TLP521-Four, see if you can change it.
1, if the central processor CPU is likened to the heart of the entire computer system, then the chipset on the motherboard is the torso of the entire body. For the motherboard, the chipset almost determines the function of the motherboard, which affects the performance of the entire computer system, and the chipset is the soul of the motherboard.
2, there are many special chips for stepper motors, and it is difficult to have a good and bad conclusion. But you're asking a lot. You should set a standardSurround others to recommend.
3, according to the number of phases to distinguish, there are two phases, three phases, five phases according to the drive mode to distinguish, there are two kinds of single-pole drive and bipolar drive, most of the chips now commonly used are bipolar drive, suitable for hybrid stepper motor drive.
4, I am currently using THB6128 to do some products, today I also checked the THB6128 datasheet this chip is very good.
1, OCV3280B is a sensorless brushless DC motor drive control chip, it integrates motor controller and driver, can achieve brushless motor control and drive, is the ideal electric vehicle motor drive control chip. OCV3280B adopts PWM four-quadrant drive mode, which can realize the positive and negative control of the motor and speed control.
2, if it is the driver chip and MCU integration of the driver there are several chip manufacturers have similar products, you can find ON Mei (8824) and Allgro these two, there are drivers that meet your application requirements. ifIs the need for some complex control functions, with a special chip may not be able to meet the requirements, need to use a single chip computer for product design.
3, Shanghai Jingfeng Mingyuan Semiconductor Co., Ltd. has a brushless motor control chip without external.
4, 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.
5, therefore, the position sensorless brushless DC motor becomesIt is an ideal choice and has a broad development prospect, but its control circuit is quite complicated.
6, the DC brushless motor 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.
