New Delhi, India – Toshiba Electronic Devices & Storage Corporation has announced a significant leap in automotive motor control technology with the commencement of engineering sample shipments for its TB9M030FG device. This new addition to the SmartMCD series is poised to redefine the efficiency and quiet operation of automotive BLDC motors, crucial for the ongoing electrification of vehicle auxiliary systems.
The TB9M030FG stands out by combining a microcontroller and a gate driver within a single, compact package. Its most remarkable feature is a proprietary sensorless approach that enables Field-Oriented Control (FOC) directly from zero speed, a critical advancement without the usual acoustic noise generated by conventional high-frequency signal injection methods.
Revolutionising Sensorless Control for Automotive BLDC Motors
The control of three-phase brushless DC (BLDC) motors presents a unique challenge, particularly when it comes to accurately detecting rotor position at very low speeds without the use of physical position sensors. Traditional sensorless control mechanisms often rely on superimposing a high-frequency voltage signal onto the drive waveform.
While effective in inferring position, this harmonic injection typically results in undesirable acoustic noise and audible motor sound, which is a significant drawback in noise-sensitive automotive environments.
Toshiba’s Innovative Noise-Free Solution
Toshiba’s latest innovation directly addresses this industry-wide issue. The TB9M030FG employs a unique sensorless control algorithm designed specifically for salient-pole motors. This method ensures stable Field-Oriented Control (FOC) not only from a complete standstill but also throughout the critical low-speed operating range.
Crucially, it achieves this without incurring the acoustic penalty inherent in existing high-frequency signal injection techniques, paving the way for quieter and more comfortable vehicle interiors powered by advanced automotive BLDC motors.
Integrated Design and Advanced Features
The SmartMCD (Smart Motor Control Device) series, exemplified by the TB9M030FG, embodies Toshiba’s commitment to highly integrated solutions for complex automotive applications. By packaging both a 32-bit Arm Cortex-M0 microcontroller and a gate driver into a single chip, the device significantly reduces component count, board space, and overall system cost.
This level of integration is paramount for modern automotive designs, where space is at a premium and reliability is non-negotiable. The compact 9×9 mm QFP48 package underscores its suitability for demanding applications.
