OUR CAPABILITIES
High-Speed Stamping for Motor Laminations
220-Ton Yadon High-Speed Press Line
Our own complete stamping line at Machohalli, Bengaluru (Bangalore) – decoiler, straightener, Yaskawa servo feeder and a 220-ton high-speed press – built for high-volume stator and rotor laminations in CRNO silicon steel and CRCA. The progressive dies on this line punch, auto-stack and auto-skew the laminations in a single pass, so stator and rotor cores leave the press as finished stacks, ready for the next process. We make motor laminations for customers across India, including EV hub and mid-drive motors, BLDC motors, ceiling and PTW fans and mixer grinders.
- 120–400strokes / min
- 0.2–1.0 mmstrip thickness
- 400 mmmax strip width
In-Die Auto Stacking, Auto Skewing & Independent Stack Heights
Our progressive tooling does more than punch electrical steel laminations. Stacking, skewing and stack-height control all happen inside the die at press speed. That removes manual handling, keeps every stator and rotor core consistent and lowers your cost per motor core.
In-Die Auto Stacking
Laminations are interlocked inside the die as they are punched and come off the press as finished stator and rotor stacks. No manual counting or stacking, tight stack-height control, accurate slot alignment and fewer handling marks – cores go straight to winding, welding or your rotor die casting.
Auto Skewing of Rotor Cores
The rotor station indexes every lamination by a set angle, so the rotor stack comes out of the die with the specified skew already built in. A skewed rotor lowers cogging torque, magnetic noise and vibration – without a skew fixture or an extra operation.
Separate Cams for Rotor & Stator
Independent cams control stack separation for the rotor and for the stator, so rotor and stator cores of different stack heights are produced in the same run. Changing a stack height is a setting change, not a new tool – ideal for motor families with several power ratings.
High-Volume Progressive Tooling
Dedicated progressive tooling for high-volume mixer grinder, table fan and pedestal fan motor stator and rotor laminations – the economical route when your volumes are high.
Servo Feeding & Quick Die Change
Yaskawa servo feeding holds pitch accuracy on 0.2–1.0 mm strip up to 400 mm wide, and the quick die change system keeps changeovers short, so both small and large batches run economically.
Secondary Operations In-House
A 40-ton Paramount hydraulic press for secondary pressing of rotors and stators, CNC rotor-shaft turning on an Ace Super Jobber 500 LM and in-house die maintenance – fewer suppliers for you to manage.
