# ATO ATO-PB-100 Single-Shaft Magnetic Particle Brake (100 N·m)

![ATO ATO-PB-100 Single-Shaft Magnetic Particle Brake (100 N·m)](https://parts.trymaglev.com/img/te-ato-pb-100.webp)

Low-cost 100 N·m single-shaft magnetic powder brake sold factory-direct by ATO; torque is roughly linear with coil current, so with a current controller it works as the absorber in a low-speed joint dyno.
