2.3.7. Active resistance of the motor phase at 200C 0,5 ± 0,1Om.

3. Structure and working principle.
3.1. ECV device.
electric cylinder consists of the following components (Figure 2):
ball screw with a rod on the end - 1;
nut ball screws - 2 with mounted permanent magnet -3;
Stator built motor - 4, is pressed into the outer casing - 5;
Sensor angular position (resolver) - 6;
terminal cable connections of the power converter to control the rotation of the ball screw nut - 7;
terminal cable connections angular position sensor - 8;


3.2. The principle of operation.
When a power converter from the control voltage to the stator windings, there is a rotating electromagnetic torque acting on the ball screw nut with the attached permanent magnets, causing it to rotate. Rotation of the nut provides a translation of the ball screw and rod. For guiding the movement of stock in the cover 9, the bronze bearing 10 to prevent rotation of stock - directing -11. For the control rod position in ECV - set resolver, sine and cosine voltage winding which is proportional to the angle of rotation nut ball screws.
