Renesas Electronics Corporation and Mineba Mitsumi have announced the joint development of resolver-based (angle sensor) stepping motor and motor control solutions, for installation in office and industry automation, and medical/nursing care equipment. These applications require motors with higher precision motor control, miniaturised form factors, and improved resistance to environmental influences. Working in collaboration, Renesas and MinebeaMitsumi have developed resolver sensor-based stepping motors and motor control solutions that address these application requirements.
MinebeaMitsumi has a strong track record with resolver sensors for automotive applications and, for the first time, has developed a new resolver for stepping motors to be used in consumer and industrial equipment applications such as robots, OA equipment, and medical/nursing care equipment. Renesas has developed a new resolver-to-digital converter (RDC) that supports MinebeaMitsumi’s new stepping motors, as well as control driver software for controlling the RDC with a 32-bit RX MCU. Renesas also provides a resolver-based stepping motor control kit, which includes development tools, including MinebeaMitsumi’s stepping motor with resolver and an evaluation board with RDC, allowing users to jump-start application development.
“I am extremely pleased that we were able to develop superb products with the cooperation of Renesas, which provides superlative control technologies,” said Katsutoshi Suzuki, technical officer, deputy officer in charge of electronics engineering development at MinebeaMitsumi: “I am hoping that this advance in product differentiation for our resolver stepping motors will allow us to acquire new markets.”
