ECEL_Model

ECEL Model

The ECEL model is used to set up the sweeping of mover position of a translational motion. To change the name of the model placed on the sheet, click the symbol on the sheet, and change the name of the component in the property window (Value field in the DeviceName line, with the Parameter Values tab selected).

The ECEL_Model contains the following parameters:

DeviceName − the name of the device model with the default name as ECEL_Model1;
MotionMax − the maximum motion range for sweeping;
MotionIntervals − the number of uniform sweeping intervals for motion range;
MotionType − the motion type: 0 for limited motion; 1: for periodic motion with full sweeping; 2 or more: for periodic motion with half or less sweeping.
MotionDir − the motion direction in (x, y, z);

The initial position set in Maxwell designs is always referred to as 0 position in ECE model. When MotionType >= 1 (for periodic motions), the number of sweepings is equal to MotionIntervals. In such a case, the last point at MotionMax is not swept and is automatically extended from the first sweeping point at zero position based on the periodic conditions. When MotionType = 0 (for limited motion), the number of sweepings is equal to MotionIntervals + 1. In such a case, the motion limit is always ranged from 0 to MotionMax in the ECE model.

An ECEL_Model cannot be used individually. It should be used combined with an ECEW_Model and/or an ECE3_Model for rotational electrical machines.

For ECE model creation, the setup of Stop Time and Timestep are ignored. At Maxwell run time, the circuit simulator assigns currents for all windings step-by-step based on the lists of current and position sweeps until all sweeps are finished. An ECE model is created automatically. You can import this ECE model in Twin Builder via the Twin Builder > SubCircuit > /Maxwell Component > Add Equivalent Circuit menu command. For more information on coupling Maxwell designs to Twin Builder components, refer to the Maxwell Equivalent Circuit Component topic in the Twin Builder Help.

Note: You can add an ECEL_Model to an existing external circuit without deleting the original circuit. In such cases, the original circuit is ignored and can be kept for future use. If you want to recover the original circuit for a transient simulation, instead of ECE model creation, you just need to deactivate each ECE related model by right-clicking the model and selecting Deactivate in the short-cut menu.
