Description

The invention relates to electrical engineering to pulsed electric motors and can be used in positional devices for moving the movable element in the plane.

The purpose of the invention is to expand the functionality by increasing the directions of movement and improving speed.

FIG. 1 shows the proposed electric motor, top view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one.

A stepping motor contains a flat ferromagnetic base 1, on which traction electromagnets are located in the form of rectangular frames 2 and 3 and external part 4 of the core, also made in the form of a rectangular frame. In the outer ends of the frame 2 there are rectangular grooves in which the windings of the traction electromagnets 5-8 are laid, and in the outer ends of the frame 3 p the rectangular grooves are laid in the windings of the traction electromagnets 9-12. Inside the frame 2 there is an inner part of the core, made in the form of a rectangular prism 13. Along the perimeter of which is a rectangular groove in which the fixing winding 14 is laid. The base of the outer part 4 of the core also has a rectangular groove in which the second fixing winding 15 is located.

Stepper motor operates as follows.

In the initial state, the locking windings 14 and 15 are disconnected and the voltage is applied to the windings of the electromagnets 7, 8, 11, 12, while the entire electromagnetic displacement mechanism takes the position indicated in FIG. 1 and 2.

If it is necessary to move the motor on a flat ferromagnetic base 1 from the left to the right, the locking winding 15 is turned on, the windings of electromagnets 7 and 8 are turned off and the electromagnet 6 winding is turned on. At the same time, the electromagnet 6 will move to frame 2 and the inner part of the core in the form of a rectangular prism 13 to the right by the step size uE .. If you need to move by the 2nd, then after that you remove

The voltage 1i from the windings 11 and 12 is applied and the voltage is applied to the winding of the traction electromagnet 10, which, attracted to the inner surface of the outer part 4 of the core, moves the frame 3, the frame 2 and the inner part 13 of the right more AT .

Then, the locking winding 14 is turned on, the locking winding 15 is turned off, the electromagnet 10 is turned off, the electromagnet 12 is turned on, the electromagnet 6 is turned off, the electromagnet 8 is turned on, and the electromagnetic movement mechanism will take the position indicated in FIG. 1 and 2, but the entire engine will generally move to the right by step 2 a. Next, the switching cycle is repeated. The reverse of the motor is carried out by changing the order of engagement of the locking windings 14 and 15.

Similarly, the motor is moved in a different direction (from bottom to top or from top to bottom), while in a certain sequence, the winding of electromagnets 5, 7, 9, 11 and locking windings 14 and 15 are switched.

For the proposed motor, it is possible to carry out stepping movements along a plane with a step size bt and 2uE.

The advantages of the invention are that by moving the engine in series of steps, the electromagnets and fixing windings switch with a frequency twice as low as the frequency of the steps of the engine, which allows, with the same switching frequency of the electromagnets, to increase the frequency of the steps, and hence the speed of the engine.

The ability to move along a plane with a step size along each coordinate B or 2LE allows the engine to move in one of 16 directions along a plane, rather than eight, as in a known device.
