Enameled Aluminium Wire Windings
Aluminium is the second of the three winding options written into every catalogue listing. This page covers what an aluminium winding involves: what the conductor’s properties mean in a winding, what the winding design must allow for, and what to confirm about the wire source when you order.
- Listed as
- Aluminium (all 9 listings)
- Applies to
- Every catalogue model
- Wire source for a specific order
- Confirmed per project, in writing
The wire options above appear verbatim in each listing’s parameter text. No cost ranking of the three wires is stated in the listings, and none is printed here.
01 The Conductor
Why aluminium windings exist
Aluminium conducts electricity less readily than copper per unit area, and weighs far less for the same conductor length — general conductor properties, stated as background. In a motor winding, those two properties set the design work: a larger conductor cross-section restores the resistance target, which asks for slot room the motor’s core design must have, and termination practice at the leads differs from copper’s. That is why aluminium winding is a design choice made by the motor maker, not a material swap performed on a copper design.
The full three-way picture — copper, aluminium and the bimetallic CCA option — is set out in the copper vs aluminium windings guide. What matters on this page is the supply discipline: confirm the wire source for your order. The company profile describes an enameled wire plant among its plants, and the listings state aluminium as a winding option — ask for the source of the wire in your motors to be named in the quotation, so the specification you validate is the one that ships.
02 Practice
Specifying aluminium without surprises
- Name it in the order: the quotation states the winding material; ‘aluminium’ on the document is what arrives in the motors
- Termination: aluminium conductors need appropriate joining practice at the leads — raise your harness and connector method in the enquiry so the lead-out arrangement is agreed
- Duty honesty: for high-duty applications, ask how the copper and CCA options compare on resistance, temperature rise and frame fit — the comparison is one email and settles the design decision on technical grounds
- Validation: treat a wire change on an existing machine as a design change; sample and re-validate before volume, exactly as with any winding substitution
None of this is hidden complexity — it is the standard engineering of aluminium-wound appliance motors.
03 Questions
Aluminium windings, answered plainly
Will an aluminium-wound motor last?
Winding lifetime is governed by temperature and insulation system more than by conductor identity; a properly designed aluminium winding in its rated duty is a mainstream, decades-old appliance practice. What shortens life is an underspecified winding in the wrong duty — which is a specification failure, not a material failure.
Is aluminium available across the whole catalogue?
Yes — it is one of the three listed wire options on every model, identical wording in all nine listings.
Can I switch an existing programme from copper to aluminium?
As a design change, yes — specified and sampled as one. Your validation confirms the machine’s behaviour before volume commits.
Specify the aluminium option properly
Pick any model and state the aluminium winding, voltage and frequency you need. The design decision for your range deserves a confirmed specification.
