AC Synchronous Gearbox & Motor Assembly

We pair gear ratio selection with the stator's torque curve at the design stage, before either part gets locked in. If a gear ratio gets chosen without accounting for what the stator can actually deliver, the finished assembly can end up underpowered or running hotter than it should across its duty cycle. As a synchronous motor manufacturer, we treat the gearbox and the stator as one engineering decision, so appliance OEMs get an assembly that performs the way it was specified to, not one that needed adjustment after the fact. 

We offer two gearbox housings and three stators, and any stator can pair with either housing using the same industry-standard mounting dimensions.

M70 Round Gearbox

The M70 is our round housing configuration. It uses standard mounting dimensions so it drops into your existing design without a new mounting interface, and it's available with a range of gear train ratios to fit different speed and torque requirements.

M80 Pear-Shaped Gearbox

The M80 is our pear-shaped housing configuration, built to the same mounting standard as the M70. It gives you a second footprint option when the M70's shape doesn't fit your enclosure, without changing how the assembly mounts or how the stator pairs with it.

Compatible Synchronous Motor Stators (Model 002, 004, 006)

Model 002, Model 004, and Model 006 stators all pair with either the M70 or the M80 gearbox.

The gearbox and stator ship as one assembly, so output shaft position, lead egress, and mounting stay consistent across a product line, which cuts down the integration work on your end when you're building multiple models on the same platform. We offer standard bushings, shaft extensions, knurled shafts, and pinions as output configurations, along with special-order geometries when your design needs something outside the standard lineup. 

Every assembly comes with three lead wire egress positions spaced 120 degrees apart, using number 22 AWG batch-tinned leads. Standard termination options are .250 inch or .187 inch spade or flag terminals. The full assembly runs on voltages as low as 24 VAC, supports 50 and 60 Hz, and carries UL recognition and CSA certification. Model 004 assemblies are also available for applications that require it.
