Global Semiconductor Solutions Supplier Ruisa Electronics (TSE: 6723) announced today that the launch of the first -via sensor driver IC series products for the use of BLDC Electric Applications. Technology can make the motor achieve zero -speed full torque without a sensor, and create a pioneer in the industry.The new motor driver IC enables Ryesa customers to design a non -transmitter -free sensor BLDC motor system with greater horsepower and speed under a given torque.In addition, power consumption has been reduced and reliability is improved. At the same time, by reducing the number of components that designers need to use to reduce costs and circuit board space.

Ruisa released three new -type motor drive ICs with new technologies this time.Among them, R, as an independent 65V, 3 -phase smart drive, can be paired with Risa or other various MCUs; RAJ306101 integrated Risa RX13T 32 -bit MCU and R, thereby reducing circuit board space and cost It improved reliability; RAJ306102 integrated Ruisa RL78/G1F 16 -bit MCU with R, bringing similar integration advantages.

Without a sensor, the ability to achieve full torque at zero speed is due to the two innovative technologies of Risa: enhanced inductive induction (EIS) can be detected in a stable position when the motor is completely stopped; when the motor is extremely low at a very low speed, the motor is extremely low speed. When running, use the motor rotor position recognition (MRI) method.At a higher speed, the new motor driver IC uses traditional methods.Both the new EIS and MRI algorithms include the cutting -edge technologies developed by Risa and are applying for patents.

Davin Lee, Vice President of The Advanced Analog Division At Renesas said: "The new sensor -free design motor IC has many advantages at the level of cost, space, power consumption and reliability. Now, our customers can need zero speed all at a total speed of zero speed. Enjoy these advantages in the torque system. This industry is the first to combine Risa to combine its technical strength with deep application knowledge to create a model that meets the solution of market demand solutions. "

The President and CEO Peter Koro? EC said: "We are very looking forward to using sensor technology in new products that once used to use sensors. It will enable us to build new products for customers based on the best size, cost and reliability. "
