Motors experiments (T212)

Subject Elec Eng

Welcome to the actuators board in the OpenEngineering Laboratory. This board contains a number of different actuators for you to control remotely and has four experiments associated with it.

Experiment 1: DC motors and the solenoid
In this activity you will investigate the performance of DC brushed motors using two different driving techniques: varying the voltage and PWM control. You will link two motors together using a solenoid, and also measure the solenoid temperature using a thermistor.

Experiment 2: Experimenting with a brushless motor
In this activity you will experiment with driving a brushless DC motor remotely to investigate its performance. You will explore different sequences for energising the stator windings of the motor. These sequences need to be correctly programmed in order to drive the motors as intended.

Experiment 3: Experimenting with a stepper motor
In this activity you will drive a stepper motor remotely to investigate its performance. You will explore different sequences for energising the stator windings of the motor, and program the sequences to drive the motors correctly.

Experiment 4: Experimenting with a servo motor
In this activity you will experiment with a servo motor and explore the response of the servo to step inputs. You will also analyse the temperature data that you collected in the first experiment.

Note that you will need to book a separate slot for each experiment.

The booking system for these experiments will be open from 6 March 2018. You will then be able to book slots for 13 March onwards. You should plan your bookings to this schedule:

  • March 13 – Experiment 1
  • March 27 – Experiments 2 and 3
  • April 17 – Experiment 4

Note that because this is the first time these experiments have been carried out at such scale, the number of available slots will be limited to begin with, so that we can monitor the performance of the system. Once we are happy that everything is working as intended, we will increase the number of slots and the variety of available times.

The link to the booking system is below.

Please note that the equipment is now in its long-term availability configuration. This means that there are fewer peices of equipment available at any one time, but they can be used for 22 hours in a day. You also should be aware that we may need to take equipment off-line with little or no notice for operational reasons. We apologise for any inconvenience if this is the case.

If you wish to check that the experiment will run at the location you intend to access it from then please visit this link using the computer, browser, and network you will use.
