Use non-confidential requirements first. Request an NDA before sending proprietary
drawings. This worksheet is planning guidance, not a product specification.

COMPANY / PROJECT

Name and business email:
Application and destination:
NDA requested before drawings: yes / no
Material / export-document review requested: yes / no
Scope: bare part / wound component / assembled component / motor program
Quantity: samples / annual forecast
Target timeline:

OPERATING ENVELOPE (state units and continuous versus peak)
DC bus voltage (V):
Continuous / peak power (kW), peak duration (s):
Continuous / peak torque (Nm), peak duration (s):

Critical dimensions and functional datums:
Mating interfaces and assembly condition:
Insulation, coating, joining and process restrictions:

COMPONENT-SPECIFIC INPUTS
Stator: core route, B-H/loss requirements, conductor/turns, connections and potting.
Rotor: vector magnet map, retention concept, temperature/load line and balance.
Housing: bearing/seal interfaces, final-condition GD&T, cooling/leak test scope.
PCB stator: layer artwork, stack-up, drill/netlist, copper, vias and terminations.

ACCEPTANCE / QUOTATION
Critical-characteristic list and sample plan:
