If you’re new to finding a professional manufacturer of electro permanent magnetic system, you probably have lots of questions. Keep reading to learn more and get answers!
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.
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.
Generally, yes, HVR MAG can do it. But also you need to provide information about the weight of the workpiece, the clearance distance between the workpiece and the carton, etc.
The adsorption force of the electro-permanent magnet produced by HVR MAG can be adjusted by the control system. Generally, there are three grades of magnetic force, which can be customized according to the actual needs of customers.
They are proportional to each other: the larger the contact area, the greater the magnetic force of the electro-permanent magnet. Normally 16kg/c㎡.
There is almost no residual magnetism in low carbon steel, but a little bit in high carbon steel. If there is a requirement for residual magnetism, we can design the product to be demagnetized with demagnetization treatment.
Empower your business to soar to new heights with our unparalleled blend of deep industry know-how, cutting-edge manufacturing prowess, and agile production timelines.
