One of Overview’s core technologies lies in a unique family of intelligent direct drive brushless DC (iBLDC) motors. The family of motors includes the Titan, Leto and Atlas motors which cover a range of power, torque and size. The iBLDC family has been developed by Overview from the ground up specifically to deliver precise, smooth and silent drive for cameras and other specialist sensors. Overview is currently the only company supplying this advanced drive technology to OEM/ODM customers.
These iBLDC motors overcome some of the problems associated with stepper motors, which have traditionally been used to drive standard PTZ cameras. In demanding applications, stepper motors are often found inadequate in terms of poor accuracy, backlash and excess noise. Steppers also require additional components such as unreliable drive belts and gears which add to design and manufacturing complexity and can cause unreliability and shorter operating life.
By contrast, Overview’s unique iBLDC motors use advanced technology based on state of the art magnetic modelling and highly accurate positional feedback. The motors deliver radically improved performance using fewer components in a smaller, more compact footprint making them easily incorporated into a wide range of products. Direct drive eliminates all belts, gears, pulleys and reduces the number of bearings, which reduces the cost of assembly and improves reliability.
