Our Independent Worm Shaft System is designed so that the shaft is now part of the gearbox and not the motor. In most cases the worm shafts are pressed onto the rotor shaft or turned on the rotor shaft itself. Therefore, the rotor assembly part of the motor is attached to the gearbox making disassembly of the rotor shaft assembly difficult. Having the VistaTec Independent Worm Shaft System allows you to keep our universal motor intact, which means no more troubleshooting a motor on the machine.
