This component models a brushed DC machine where the field is set by a permanent magnet.
| Connection | Description |
|---|---|
| + (vp), - (vn) | Positive and negative armature terminals. |
| omega (shaft coming out of machine) | The voltage on this pin 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 N•m. |
| θ (theta) | Measurement pin for the shaft angle in radians. |
| Ea | Measurement pin for the back-EMF voltage. |
This component should only be used in transient-type simulations where Initial conditions are set to User defined.
