Hargrave HT|8
Hargrave Technologies' HT|8 is a brushless motor for UAV propulsion. It is available in semi-enclosed and open-frame versions with 85, 100, or 125 KV windings.
The motor offers sustained thermal performance and repeatable output under load, and is designed around heavy-rare-earth-free magnets to reduce dependence on constrained materials. Development testing used installed propellers, sustained full-thrust operation, and rapid load changes.
