Product Description
OD:49mm frameless motor
This 49mm outer‑rotor frameless torque motor provides high torque‑density performance powered by standard 48VDC industrial supply. Rated 38W output power with 1.1Nm torque and 1820 RPM operating speed. Adopting housing‑less split stator‑rotor construction, this frameless motor can be directly embedded into customer‑designed mechanical assemblies. It removes bulky motor housing to minimize overall machine dimension and weight, perfectly solving space‑limited design challenges. With low cogging torque and smooth rotation output, it delivers reliable precision motion for industrial equipment. Custom modification and volume‑order support are available for system integrators, robot developers and equipment manufacturers.
Customization is available upon request for this motor series, including but not limited to rated voltage, speed, torque, lead wire specifications, outlet orientation, shaft configuration, encoder/sensor integration, and more. Please provide your specific requirements, and we will offer a tailored solution for you.
