GearTorq™ is Alva's slotless frameless motor series engineered for geared applications and actuator systems used in professional unmanned platforms. Designed to integrate directly with transmission assemblies, the motors feature a central gear mounting architecture that supports compact mechanical layouts while enabling efficient torque transfer. The slotless electromagnetic design eliminates cogging torque, providing exceptionally smooth motion that is well suited to precision positioning and controlled actuation.
The GearTorq™ series combines high power density with an industry-leading motor constant relative to rotor inertia, helping actuator designers achieve rapid dynamic response without unnecessary weight. Available in multiple frame sizes, the motors are suitable for integration into electromechanical actuators and other geared drive systems where efficiency, responsive control, and compact packaging are important design considerations for uncrewed applications.
