T-Motor CubeMars RI80 KV75 Brushless DC Inner Runner Robot Joint Motor (with Hall sensor)

This high-performance frameless BLDC inrunner motor is designed for advanced motion control applications such as cobot arms and exoskeleton systems. Built with a delta winding configuration and optimized for FOC (Field-Oriented Control), it delivers smooth, precise, and efficient operation. With a rated torque of 1.45Nm and peak torque up to 4.1Nm, it ensures powerful performance in a compact form factor. Its robust insulation, wide operating temperature range, and high torque-to-weight ratio make it ideal for robotics, automation, and precision engineering applications.
