➀ EPC releases EPC91118 GaN motor drive for robotic joints, integrating control MCU, magnetic encoder, and power stage on a 32mm PCB;

➁ The 15-55V board uses three 100V EPC23104 half-bridge ICs, RS485 communication, and eliminates electrolytic capacitors via 100kHz PWM operation;

➂ Designed for robot wrists and drones, available via Digi-Key with ceramic-only DC-link for compactness and efficiency.

➀ Nidec opened a 108,000m² motor and inverter factory in Qingdao, capable of producing 18 million motors and 20 million inverters annually;

➁ The facility integrates production, R&D, and logistics, focusing on industries like home appliances, refrigeration, and automotive electronics;

➂ Plans to expand to automotive electronic manufacturing and collaborate with local governments for new opportunities in China.

➀ Renesas launched the RA2T1 MCU, a 64MHz Arm Cortex-M23-based microcontroller designed for single-motor applications like fans, power tools, and home appliances;

➁ Features include three-channel current sensing, PWM with dead-time control, safety mechanisms for over-current protection, and reliability enhancements like ADC self-diagnosis and SRAM parity checks;

➂ Supports voltage ranges from 1.6V to 5.5V, offers up to 64KB flash memory, and includes software tools for seamless integration with legacy code and RTOS.

➀ Researchers from the Institute for Molecular Science have improved the speed of DNA-nanoparticle motors by optimizing their design, bringing them closer to the speeds of natural motor proteins.

➁ The DNA-nanoparticle motor uses the 'burnt-bridge' Brownian ratchet mechanism, where the degradation of RNA/DNA bonds propels the motor forward.

➂ By increasing the concentration of RNase H, the speed of the motor was significantly enhanced, though it came at the cost of reduced run length and processivity.
