A comparison of the torque-speed characteristics for five different motor types. To select the motor type, right-click on the Electric Motor block, select Variant->Override using and then the desired motor. All motors have been sized for roughly the same mechanical power rating.

An induction machine used as a wind turbine generator. The Simple Turbine block converts wind speed to turbine output power by a simple output power versus wind speed characteristic.

Control and initialize a Synchronous Machine (SM). The test circuit shows the SM operating as a generator. The terminal voltage is controlled using an AVR and the speed is controlled using a governor.

How to use the Stepper Motor Driver and Stepper Motor blocks together to implement a controlled permanent magnet stepper motor. The model provides two controller options: one to control position and one to control speed. To change the controller type, right-click on the Controller block, select Variant->Override using-> and select Position or Speed.

A test harness for a Permanent Magnet Synchronous Motor (PMSM) drive sized for use in a typical hybrid vehicle. The test harness can be used to determine overall drive losses when operating at a given speed and torque. Tabulated losses information from this test harness can then be used by the Simscape™ Electrical™ Motor & Drive (System Level) block for rapid simulation of complete drive cycles whilst still accurately predicting overall system efficiency.

How manufacturer data for torque as a function of current and angle can be used to model a torque motor. The datasheet shows linear characteristics for rotor angles between 20 and 70 degrees and for currents where saturation does not occur. Data in this range is used to parameterize the simplified model of the torque motor. Using MATLAB® to process the data points extracted from the datasheet, we can convert manufacturer data into motor parameters that are often obtained from finite element software.

Parameterize and tune a stepper motor using manufacturer datasheet information and a test harness. The model is parameterized using numerical data extracted from a datasheet. The simulation generates pull-in torque characteristics that you can compare to a manufacturer-provided pull-in curve. To tune the stepper motor model, the example uses a test harness that varies the drive type and load parameters.
