Resolver-based step motor controllers handle heavy loads without step-out
Renesas Electronics Corporation and MinebeaMitsumi Inc. announced the joint development of resolver-based (angle sensor) stepping motor and motor control solutions optimized for use in robots, office automation (OA) equipment, and medical/nursing care equipment. These applications require motors with higher precision motor control, miniaturized form factors, and improved resistance to environmental influences. Working in collaboration, Renesas […]
Motor field-oriented control, Part 1: Principles
Field-oriented control, also known as vector control, is a calculation-intensive algorithm for motor control which is now practical due to advances in ICs; it offers improved efficiency along with superior control of torque and other performance parameters. Motor control—and doing so accurately and efficiently—is a topic of great interest. Field-oriented control (FOC), sometimes called vector […]
