FAQ

Click "Manufacturer Website" to go to the brand's official product page, where you can buy online or contact their sales team directly.
A frameless motor ships as a separate stator and rotor, without a housing or bearings, so it is integrated directly into the joint or assembly. This model is 25 mm in diameter and is press-fit or bonded into the customer structure, which keeps the package smaller and stiffer than a housed motor.
It delivers up to 0.072 N·m of peak torque with a rated torque of 0.024 N·m, and a KV of 600 rpm/V. Rated voltage is 16 V. Match these against your continuous and transient joint loads before selecting.
