About Westmag
Westmag develops electric motors, actuators and associated power electronics around the torque, speed, weight and environmental requirements of a specific autonomous platform. Its engineering spans electromagnetic design, mechanical packaging, controls, testing and production rather than separating the motor from the wider drive system.
The company is establishing domestic manufacturing for drone propulsion and robotic motion hardware using US and allied supply chains. Customers work with Westmag from early performance modelling through prototypes, qualification and scaled production of application-specific drives.
