It claims this new line of gear motors delivers the highest performance with the lowest power budget.

The door lock motors deploying this hybrid worm gear provide the highest performance in all critical design parameters; life cycle, pull off force, TIR and twisting torque. This new door lock motor product line also provides a viable alternative to brass worm gears in the most demanding applications.

“This innovation fills the performance gap between the current plastic gear and brass gear motor designs,” said Jim Dick, Johnson Electric’s head of strategic marketing, “High reliability and low power budget are the critical factors in door lock design,” he added.
