Worm Gear Screw jacks can be driven by a handwheel or motorised by connecting electric motors through a B14 flange or a B5 bell housing with coupling.
Commonly motors are AC 3 phase although 1 phase and DC motors are also possible. Servo motors can be integrated and their high speeds and performance are useful with ball screw jacks. Brake motors are occasionally needed where fast stopping is required or if the screw jack is not self-locking.
