Hollow Cup Motors
Dexterous hands / drones / medical · OD 8 — 30 mm · low inertia, high response
DESCRIPTION
Hollow cup (coreless) motors carry no iron in the rotor. The result: very low inertia, small electrical time constant, fast start-stop response, high efficiency, low electromagnetic noise. Common in dexterous robotic finger joints, medical handheld instruments, and consumer drone servos. We supply OD 8 — 30 mm with optional gearhead (planetary or harmonic) integration.
