About this motor
The H-Frame is the motor most desert coolers in North and Central India are built around. It uses a 139 mm stamping, a rolled mild-steel shell with a welded mounting pad, and die-cast aluminium end shields that carry a ball bearing on each side.
We build it in three stack sizes. The stack is the height of the stamping pack inside the motor: a taller stack gives more torque for a bigger blade. 32 mm covers the common 18 inch cooler, 35 and 38 mm are picked for larger blades and longer running hours.
Where it is used
- Desert coolers with 18 to 24 inch blades
- Large room and shop coolers
- Coolers built for rental and tent-house duty
- Replacement motor for standard H-Frame bodies
Recommended blades: Climatizer, aluminium or CRCA steel fan blade, 18 to 24 inch, matched to the stack size.

Questions about the H-Frame
What does 32 mm mean on an H-Frame cooler motor?
It is the stack size: the height of the stamping pack in the stator. H-Frame motors all use the same 139 mm stamping; a 35 or 38 mm stack has more iron and copper/aluminium than a 32 mm and drives a heavier blade.
Which H-Frame motor suits an 18 inch cooler?
The 32 mm stack is the standard fitment for an 18 inch desert cooler. For 20 to 24 inch blades or coolers that run all day, buyers usually move to 35 or 38 mm.
Is the H-Frame motor 3-speed?
Yes. The speed winding is tapped for high, medium and low. Lead colours are blue common, black high, white medium and red low.
