We manufacture stators used for BLPM and AC motors and alternators from 24 to 230 V.
Stators are wound by hand and by machine, but hand winding is being phased out in line with investment dynamics. This will reduce production costs and significantly increase quality, which is checked in the process with a control device that also enables keeping statistics.
Stators are manufactured using modern Statomat winding machines (type A2), which are computer-controlled and can therefore be quickly adapted to a new stator type. For the production of stators, an insulation machine, a coil winding machine, a stator pack coil machine, intermediate and final calibration machines, a wire stripping machine, a varnishing and painting machine, a welding machine and a control device are used.
The stators are manufactured in several steps – first, the insulation is inserted into the stator stack; in the meantime, the coils have already been wound by the winding machine and are transferred to the insertion machine. The latter inserts the coils into the stator stack and fills the slots in the stack with insulation.
Afterwards, the operator calibrates the stator, which is then transported to the other line, where the stator taps are prepared, final calibrations and controls are performed, and the stator is readied to be enamelled. The stators are bath-enamelled (impregnated) and dried in an oven.
Afterwards, the stators are painted; before we ship them, we perform a final inspection. We ensure the high quality of our products throughout the manufacturing process. To this end, we perform a 100% electrical inspection of electrical faults, inter-coil and inter-phase short circuits, as well as coil inductance.
The inspection is performed on an inspection machine – before the impregnation step, as well as at the end of the process.
Our system of quality is certified according to ISO 9001:2008.
