INTERFACING AND PROGRAMMING OF STEPPER MOTOR
AIM: To run a stepper motor at different speed in two directions.
APPARATUS REQUIRED:8086 p kit, stepper motor, Interface board and Interface chord.
THEORY:A motor in which the rotor is able to assume only discrete stationary angular
position is a stepper motor. They are widely used in a variety of applications such ascomputer peripherals and in the area of process control machine tools, roboticsetc..
2 phase scheme:In this scheme any two adjacent stator windings are energised. There are two
magnetic fields active in quadrature and none of the rotor pole faces can be in directalignment with the stator poles. A partial but symmetric alignment of the rotor polesis of course possible.
Typical equilibrium conditions of the rotor when the windings on 2successive stator poles are excited. In step(a) A1 and B1 are energised .The pole faceS1 tries to align itself with the axis of A1(N) and the pole face S2 with B1(N) .Thenorth pole N3 of the rotor finds itself in the neutral zone between A1(N) and B1(N) .S1 and S2 of the rotor position themselves symmetrically with respect to the two
stator north pole.Next. When B1 and A2 are energised . S2 tends to align with B1(N) and S3
with A2(N), of course again under equilibrium conditions.Only partial alignment ispossible and N1 finds itself in the neutral region , midway between B1(N) and A2(N)(in step (b)). In step(c), A2 and B2 are on. S3 and S1 tend to algin with A2(N) andB2(N), respectively, with N2 in neutral zone. Step(d) illustrates the case when A1 andB2 are on.
ALGORITHM:
1.
Load the input data.
2.
Move the count value to B register.3. Send data to the output device through port.4. Call the delay program5. After the delay time load the next data and repeat the same.6. By changing the delay time we can change the speed.

A 3:8 decoder 74LS138 is employed to generate I/O decoding logic. The addresslines A3, A4, and A5 are tied to pin 1, 2, 3 of 74LS138 respectively. The address linesA6 and A7 are NANDed together and the NAND gate o/p is connected to pin 5 of74LS 138.similarly IOW and IOR signals NANDed together and the NAND gate o/pis connected to pin 6 of 74LS 138. Pin 4 is grounded.
