1 Electric Solenoids Force  stroke -1

2 Electric Rotary Actuator (solenoid)

3 Electric Rotary Actuators (motors) DC motors AC motors –stepper (2-phase synchronous) –brushless (3-phase synchronous) –induction

4 Step Motors

5

6 Step Motor 12 step/rev, 1 phase on

7 Step Motor 12 step/rev, 2 phase on

8 Step Motor 12 step/rev, half-stepping

9 Step Motors

10 Selecting Step Motors Torque Speed Current Lead configuration

11 Torque/Speed

12 Series/Parallel Wiring

13 Step Motor Drives Resolution (full, half, microstepping) Current Limit (resistor or digital) AC powered or DC powered Pulse/Direction or Indexing

14 Resolution Full step/Half step Microstepping –x2,x4,x5,x8,x10,x16,x25,x32,x50,x64,x125,x128,x 250,x256 common choices Max step frequency –PLC: 7kHz pulse rate => 2100 RPM at x1, 8.2RPM at x256 (1.8deg motor) –Compumotor 6104: 2MHz pulse rate => 2300RPM at x256 Resonance problems
