An electro permanent magnet contains two kinds of magnetic materials, using electricity to actviate or deactivate its own magnet field. It combines the properties of a permanent magnet and the ease of control of an electromagnet.
Both industrial magnets are electrically switched on/off. The main difference lies in 2 points.
First, electromagnet works on consistent electric power; if cutting off the power supply suddenly, it losses magnetic force. What distinguishes electro-permanent magnet from electromagnet is that the former does not use electricity during working. If cutting off the power, it can remain holding/lifting/gripping/clamping of the load.
Second, due to continuous power input, electromagnet has heat generation which might affect its workholding effectiveness during machining. Whereas that is no problem to EPM.
For an electro permanent magnet, the magnetic force still remains in the event of a power failure, which is to say, in lifting or workholding applications, the ferrous load or workpiece, will stay lifted/clamped, no need to worry about the falling off.
Moreover, the magnet cannot be deactivated until the electrical power is restored.
Higher Safety: Insusceptible to a sudden power failure/outage, the magnetic force remains during work. No dropping of a suspended load, workplace safety guaranteed.
Convenience: No battery back-up system is required.
Energy Saving: Only uses electricity for a few seconds during the MAG and DEMAG phases. No electrial power consumed during work. The electrical consumption is 95% less compared to a traditional electromagnet.
HVR MAG has established longterm relationships with our customers worldwide, not only for current business, but also for developments in the long run. Each electro permanent magent we produced, we treat it as our child, and will track the running condition with its unique ID number when been delivered to our customers. We take good care of them and grow up together with them. You may find this a bit unreal. But if you choose HVR MAG, your experience will justify it.
Some of HVR MAG's local agents can provide technical services.
Professional engineers can be delegated to provided installation assist.
Technical Window Consulting available at any time from HVR MAG.
Our engineering team is backed up by European professors.
Our quality management system is set up in strict accordance with ISO 9001:2015 standard.
Each product manafactured has to go though seriously material check and quality inspections before delivery.
