New technology enhances horsepower, efficiency, speed, and reliability; Simultaneously reducing costs and reducing circuit board space
Global semiconductor solution provider Renesas Electronics (TSE: 6723) announced today that it has launched the first sensorless motor driver IC series products suitable for brushless DC (BLDC) motor applications. This series adopts Renesas‘s patented new technology, which enables motors to achieve zero speed and full torque without sensors, pioneering the entrepreneurial world. The new motor driver IC enables Reza customers to design sensorless BLDC motor systems with greater horsepower and speed at a given torque. In addition, it also reduces power consumption, improves reliability, and reduces costs and circuit board space by reducing the number of components that designers need to use.
Renesas has released three new motor driver ICs using new technologies. Among them, RAA306012, as an independent 65V, 3-phase intelligent driver, can be paired with Renesas or various other MCUs; RAJ306101 integrates the Reza RX13T 32-bit MCU with RAA306012 in a single package, reducing circuit board space and cost, and improving reliability; RAJ306102 integrates the Reza RL78/G1F 16 bit MCU with RAA306012, bringing similar integration advantages.
The ability to achieve full torque at zero speed without the need for sensors is thanks to Reza‘s two innovative technologies: Enhanced Inductive Sensing (EIS), which can provide stable position detection when the motor comes to a complete stop; When the motor is running at an extremely low speed, the motor rotor position recognition (MRI) method is used. At higher speeds, the new motor driver IC adopts traditional methods. The new EIS and MRI algorithms both include cutting-edge technologies developed by Renesas that are currently being patented.
Davin Lee, The Vice President of the Advanced Analog Division at Renesas states: "The all-new sensorless design of motor driver ICs offers many advantages in terms of cost, space, power consumption, and reliability. Now, our customers can enjoy these advantages in systems that require zero speed and full torque. This industry initiative is the result of Renesas combining its technological strength with profound application knowledge to create a model of solutions that meet clear market demands."
Peter Koro, President and CEO of Domel Inc, a global supplier of motors, vacuum cleaner motors, blowers, and components š EC said, "We are very much looking forward to adopting sensorless technology in new products that used to require sensors. Renesas‘ breakthrough will enable us to build new products for customers based on optimal size, cost, and reliability."
