This component models a brushless DC machine. This is a type of permanent magnet synchronous machine with a trapezoidal back-EMF profile.
It is modeled in the ABC coordinate frame (that is, it is not transformed).
| Connection | Description |
|---|---|
| A, B, C | The three-phase connection to the stator. |
| shaft (shaft coming out of machine) | Mechanical connection to the shaft. The voltage represents the mechanical angular speed in rad/s. You can attach mechanical loads, sensors, or motion controllers to the motor through this pin. An external load may also be applied using appropriately connected voltage/current sources. |
| Te | Measurement pin for the Electromagnetic torque in Nm. |
| θ (theta) | Measurement pin for the shaft angle in radians. |
This component should only be used in transient-type simulations where Initial conditions are set to User defined.
