Toshiba Corporation has announced the TB9080FG, a three-phase brushless motor pre-driver integrated circuit for general automotive applications, that allows the motor to operate with low noise and high efficiency through sine wave drive and advance angle control1. The product is scheduled to put into mass production in September this year. For vehicles equipped with an idling reduction system, the engine noise of the vehicle disappears when the system is activated, while the noise of the car air conditioner is more audible. Despite the urgent need in the market for a method of reducing air conditioning noise, mechanical solutions such as optimizing the main source of noise - the blade shape of the blower fan and the noise reduction material in air ducts fail to achieve low noise goals. The TB9080FG replaces 120 degree square wave control with sine wave control, which electronically reduces the noise of the blower fan motor. Optimized advance angle control also helps improve motor operation. Product main features 1. Sine wave control to reduce noise Sine wave control with third harmonic helps the motor run more quietly. 2. Digital filter to prevent over-the-counter motor 2 The digital filter circuit controls the external PWM3 signal, ensuring the motor starts slowly and avoids overshooting. 3. Built-in 16 kinds of rotation of the datasheet The built-in datasheet supports the use of motors of all poles (from 4 poles to 12 poles). 4. Optimized advance angle control to achieve high efficiency The motor current is measurable and the advance angle is automatically controlled in increments of 1 degree to help increase the motor's rotational efficiency. 5. Motor speed feedback control can increase speed accuracy The motor speed is controlled by comparing the target value with the signal from the external Hall element sensor 4. The main specifications Product Type: TB9080FG Sample price: 400 yen (tax included) Production plan: September 2013 Production volume: 3 million / year Channels: 6 channels (boost DCDC high: 3 channels, low: 3 channels) Standby current: 50μA (sleep mode, Ta = 25 ° C) Operating voltage range: +7, -18V Operating temperature range: -40, -125 ° C Speed ​​Input Signal: The external PWM ratio or DC input voltage value is used as the target speed and the integrated circuit compares the speed (Hall element signal) accordingly and controls the motor speed. Drive Control: Drive the sine wave by generating the third harmonic Detection circuit: overcurrent detection, overheating detection, overvoltage detection, VCC low voltage detection, internal and external temperature detection, external temperature limit circuit and motor lock detection Diagnostic circuit: Uses the 10Hz signal and the PWM duty ratio previously determined according to various abnormal modes to output the error message. Package: LQFP64 (12mmx12mmx1.4mm) As bicycles become more and more popular, their construction and accessories are becoming better known. Some of the Bike parts require regular maintenance or replacement, such as the chain and brake panels. Proper chain tension is essential for efficient power transfer from the pedals to the rear wheel. If the chain is too loose, it can lead to slippage and loss of power. If it is too tight, it will cause unnecessary friction and wear on the chain and bike freewheel. The chain tensioner is a key component in maintaining the correct tension in your bike's chain. It ensures that the chain runs smoothly and does not slip or jump off the sprocket. And the bottom bracket is the central component that holds the crankset (the pedals and gears) in place and allows it to rotate. A well-functioning bottom bracket is vital for a smooth and efficient ride. If the bottom bracket is worn or damaged, even rainy riding causes seepage, it can cause friction, creaking noises, and even prevent the crankset from rotating properly. So it's important to check the bike status in time to ensure safe riding. We have almost all the parts for the whole bike, the bike stem in alloy, the seat post in multi-size and so on. bicycle parts,bike chain,chain tensioner,bottom bracket,BMX MID BB Suzhou Jingqiyao Intelligent Technology Co., Ltd. , https://www.jingqiyaoparts.com
