Motor Torque-Speed Curves
A comparison of the torque-speed characteristics for five different motor types. To select the motor type, right-click on the Electric Motor block and select Block Parameters (Subsystem) from the context menu. In the new window, specify the desired motor using the Label mode active choice parameter. All motors have been sized for roughly the same mechanical power rating.

Three-Phase Synchronous Machine Control
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.
Stepper Motor with Control
Model a controlled permanent magnet stepper motor by using the Stepper Motor and Stepper Motor Driver blocks. The model has two controller options: one to control position and one to control speed. To change the controller type, right-click the Controller subsystem, select Variant > Label Mode Active Choice, and then select Position or Speed. The stepper has a full step size of 1.8 degrees. In position control mode, the input to the Ref port is the desired number of steps. In speed control mode, the input to the Ref port is the desired number of steps per second.
HEV PMSM Drive Test Harness
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.
Torque Motor Parameterization
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.
Stepper Motor Pull-in Characteristics
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.
