Q: What is the power and what is the level of protection?
A: TI products are many, to be specific to the model specific analysis

Q: Is there a driver for DRV2605? thank you
A: Email phone contact me here.

Q: Where can I download the details?
A: You can log in to China Power Grid after the meeting, and we will upload the speech materials to the playback page for everyone to download and learn free of charge

Q: How much brushless motor efficiency?
A: The efficiency of the motor η= (1-∑P) ×100% formula ∑P is the total motor loss, ∑P= (PFe (iron loss) +PFw (mechanical resistance loss) +PCul (rated copper loss) +PCu2 (maximum copper loss) +PS (reactive power loss)) /P1; P1 input power to the motor.

Q: Can it be used in the robotics industry?
A: TI has many applications in the robotics industry

Q. Are there any classic examples of smart homes?
A: There are many applications, such as smart door locks, automatic curtains and so on

Q: Hello, just now you said that the PWM frequency of DC brush motor depends on the motor parameters, my 24V motor inductance is 3.6mH, rated current 2.3A, starting current 13.5A, what other parameters are needed? What PWM frequency is appropriate for such a motor?
A: The duty cycle of the PWM pulse determines the speed of the motor, and changing the duty cycle can change the voltage added to both ends of the motor, so as to change the speed, you can determine the duty cycle of the input PWM according to your needs.

Q: Does the drive circuit have an integrated drive algorithm?
A: Some integrated drive algorithms, such as DRV8308, DRV10 series, integrated brushless DC motor control algorithm

Q: How to deal with the back electromotive force in the case of braking? Is there a protective circuit inside the driver chip?
A: TI many specifications have introduced the braking principle. The characteristic of TI products is that the protection mechanism is relatively complete

Q: Does the motor drive have the function of controlling the motor brake?
A: Yes

Q: Are there any cases of drones
A: Yes, you can communicate with us by email or phone

Q: What about power consumption?
A: TI products are many, there are specific to specific products

Q: If the single direction is driven for a long time, rather than the pulse drive, is it harmful to the driver chip itself?
A: Many TI stepper driver chips are integrated MOS, and the long-term drive in a single direction, that is, the fixed working state of a certain MOS for a long time, will cause the MOS to be in a hot state.

Q: Is it direct drive or add other chips?
A: TI has a lot of motor drive products, many of which are integrated with MOS for direct drive, and a lot of front-drive products.

Q: Does it have emergency brake control?
A: There are many TI motor drive products, and many products have this function.

Q: What is the control accuracy of TI motor?
A: There are many kinds of control methods for TI motor drive, depending on the specific model and specific product.

Q: Is there a motor speed signal returning?
A: Yes, specific to your application, you can contact us by phone or email.

Q: What is the operating voltage of this type of motor?
A: TI motor drive products are mostly low-voltage products below 70V

Q: Is there any case of variable frequency drive of asynchronous motor used in industry?
A: At present, I have not contacted it, you can send an email to us to see if you can help provide it in the future.

Q: What are the main applications of these motors ？？？？？
A: It is widely used, and TI's motor drive products are mainly for applications below 70V

Q: For high-power motors, can the driver chip be protected in time when the motor is blocked?
A: This is related to the selection of the driver IC, including the size of the working current of the driver IC, and TI products have measures such as overcurrent protection

Q: What kind of drive is good for power above 5 kW
A: TI motor drive is used for products below 70V

Q: How accurate is this
A: It depends on the type of motor and drive IC you choose

Q: Hello: What products does TI motor driver's product line include?
A: TI motor driver's product line is very complete, brushed DC, stepping, brushless, Hall, etc., if there is a specific use of the need for selection welcome to contact us.

Q: How long does the chip last?
A: The life of the chip has a lot to do with your application products and applications

Q: Is there a BLDC solution, and which chips are corresponding?
A: There are many BLDC programs, you can contact us by email or phone if you need information.

Q: How to drive the motor?
A: All work according to the principle of electromagnetic induction

Q: How much margin should the motor drive leave?
A: The voltage is generally doubled, such as the driver chip of 48V and above for a 24V motor

Q: What is the rationale
Q: What are the advantages of TI's products in terms of response speed and operating temperature?
A: Depending on the product TI general product operating temperature range -40 to 85, car gauge products such as DRV8305, the temperature range can reach -40 to 150

Q: What is the maximum driving current of the motor drive?
A: It is related to mos tubes, and different mos tubes require different driving currents
