Description
Nomex + Mylar + Nomex (NMN) Insulation
Indeed, NMN insulation is a laminated sheet material with a polyester film core sandwiched between two Nomex aramid paper layers, used as slot liner and phase insulation in motor rewinding.
NMN Insulation Details
- 4 laminate combinations: 2-2-2, 3-3-3, 3-5-3 and 5-5-5
- 4 total thicknesses, from 0.15mm to 0.38mm
- Three-layer Nomex–Mylar–Nomex construction
- Pricing is per metre; a quantity of 1 equals 1 metre
- P/N: NMN
Specifically, choose the laminate combination and thickness that match the slot clearance, dielectric requirement and thermal class of the winding being rewound.
Motor Rewinding Applications
Overall, NMN insulation such as this suits a wide range of motor rewinding and repair applications, including:
- Electric motor rewinding and repair
- Stator and armature winding insulation systems
- Motor manufacturing and refurbishment
- Industrial and mining motor overhauls
- Pump and fan motor rebuilds
Because Nomex is a heat-resistant aramid material, however, this laminate suits higher thermal-class windings than an equivalent Dacron-faced sheet. Consequently, it is often specified alongside Nomex slot wedges on the same rewind.
