Electro-permanent direct current:
These electromagnets in their standard models are manufactured at a voltage of 24vdc, but on demand they are manufactured at any voltage, these unlike the IMAVEM models do not require power supply for the generation of the magnetic field, this power supply will only be used to annul the magnetic field and thus be able to release the piece.
In this case, the electrical connection time is very short, as only short pulses are required to release the load. They can also be used with long working coefficients or even continuously if required.
These electromagnets are used for automation, robotics, manipulation, safety, etc.
They are also important where, for safety reasons, safety is required in the maintenance of the field, even if there is a power failure.
Features:
Degree of protection IP65
Thermal Class B (130)
Rated voltage 24V DC
Normalised Duty cycle: see table
For other voltages, ED or sizes, please consult us.
A permanentelectric electromagnet is a device aimed at transforming electrical energy into mechanical energy. Direct current electromagnet are produced in ferric alloys and operate at 24 V. Their functioning is very simple: their magnetic field is concentrated in iron armature, thus permiting any type of pick-up. When it is connectes to the current, this magnetic field is eliminated, allowing the charge to release. When the tension increases, the magnet recovers its initial strenght.
Supply possibilities on request:
Standard terminals included free-of-charge, for all sizes.
IMAVP20/ND,IMAVP30/ND, IMAVP40/ND: 2×0,25mm2
IMAVP50/ND, IMAVP65/ND, IMAVP100/ND: 3×0,5mm2
IMAVP150/ND: 2×0,75mm2
For operating factors and voltages other than standard, deviations from the standard installation or other sizes, please consult us.
The following table gives the holding force values (Fm) according to the air gap (δL) and measured under the following conditions:
- Dc supply (DC).
- Flat holding piece (<3μ roughness) in AºSt37, the thickness of which is indicated in the table and dimensions to be greater than the magnetic face of the electromagnet.
- 20 ° C ambient temperature.
- Coil stabilized at its working temperature.
Under any other conditions, the magnetic force (Fm) may decrease.
