Robust D91127 Brushed DC Motor from China Suppliers | Factory for High Torque Applications
Production Introduction
As a compact high efficient brushed DC motor, we offer two version magnets, magnets made of NdFeB (Neodymium Ferrum Boron) option, it provides more robust torque comparing to conventional ferrite magnets. Another option is made of ferrite which is economical.
⚡
NdFeB magnets deliver superior torque vs. standard ferrite — ideal for demanding applications.
It is durable for harsh vibration working condition with S1 working duty. Tight shaft end play feature allows its special application for tight axial movement. Stainless steel shaft, and anodizing surface treatment can be customized made.
