Overview
Electric Motors & EV
Electric motors, from ceiling fans and pumps to EV traction motors, depend on a secure joint between shaft and rotor. A straight form knurl on the shaft creates an interference fit that transmits torque without keys or adhesives, and does it in a single turning operation.
As India scales EV and two-wheeler production, motor and reduction-gear makers need knurling tools that hold size in high volumes and gears that run quietly.
Advantages
Why motor makers choose us
Keyless torque transmission
Straight knurls lock rotor, commutator and gear onto the shaft.
One-operation process
Knurl on the same CNC lathe that turns the shaft.
Quiet drives
Ground and helical gears for reduction stages.
Built for volume
Consistent knurls across long production runs.

Applications in Electric Motors & EV
Press-fit knurling on motor and pump shafts
A straight knurl on the shaft locks rotor cores, commutators, impellers and couplings in place without keys, adhesives or splines.
Gear hobbing
Hob cutters generate spur and helical gears for gearboxes, pumps, machinery and vehicles.
EV and e-axle reduction gears
Precision ground and helical gears for the reduction stage between an electric motor and the wheels.
