Magnetic Couplings

May 08, 2025

Magnetic couplings are widely used in wind energy, hydrogen energy, lithium batteries and photovoltaic systems. It is composed of an inner magnetic rotor and an outer magnetic rotor, with a non-magnetic isolation sleeve in the middle. Two sets of magnetic rotors are coupled through magnetic fields.
When the driving end rotates, the magnetic field drives the driven end to rotate synchronously, thereby achieving power transmission. The entire process has no physical contact, thus avoiding wear and leakage problems. It is widely used in wind energy, hydrogen energy, lithium batteries and photovoltaic systems.

1. Core Advantages

Non-contact magnetic transmission, zero mechanical friction, zero component wear, ultra-long service life
Isolation sleeve completely separates medium and drive side, zero leakage, solve toxic, volatile, corrosive liquid sealing problems
Built-in automatic overload slipping protection, avoid motor damage caused by stuck rotor
No lubricating oil needed, no medium contamination, suitable for food, pharmaceutical and cleanroom standards
Isolate vibration between driving and driven shafts, reduce equipment operation noise
Multiple installation forms: shaft connection, flange connection, split quick disassembly structure
Custom torque, shaft bore, isolation sleeve material according to working medium
Anti-corrosion isolation sleeve options: 316 stainless steel, titanium alloy, PTFE plastic

Chemical Industry: Corrosion resistant magnetic pump, sealed reaction kettle stirring transmission
