PS motor

NAVIGATION: Motor > PS motor

There are two methods of creating a motor data set for the rotary synchronous motor.

Vorgehensweise: Motor calculation

Enter motor data
The motor data relevant to the calculation must be entered manually from the data sheet.
Click the "calculation" button.
If the moment of inertia of the motor P 0461 Mot_J is not known, a value roughly corresponding to the motor's moment of inertia must be applied.
The calculation process be observed on the DriveManager 5 by choosing the View, Messages menu.
Calculation of operating point:
P 0462 MOT_FLUXNom nominal flux,
Calculation of: current, speed and position control parameters

ATTENTION:
All existing motor parameters are overwritten.

Calculated values

Flux settings (including for torque constant)
Control settings for current controller:
The current controller is dimensioned dependent on the switching frequency setting.
Speed controller and position controller gain:
In this, a moderately rigid mechanism and a 1:1 moment of inertia adjustment from the load to the motor are to be assumed.
V/F characteristic

ATTENTION:
All existing control parameters are overwritten.

Parameters

P. no.	Parameter name	Function
P 0490	MOT_IsLinMot	Selection for rotary or linear system
P 0450	MOT_Type -> PSM	Motor type (ASM, PSM)
P 0451	MOT_Name ¹⁾	Freely selectable motor name
P 0455	MOT_FNom ²⁾	Rated frequency of the motor
P 0456	MOT_VNom ²⁾	Rated voltage of the motor
P 0457	MOT_CNom ²⁾	Rated current of the motor
P 0458	MOT_SNom ²	Rated speed
P 0459	MOT_PNom ¹⁾	Rated power
P 0460	MOT_TNom ²⁾	Nominal torque
P 0461	MOT_J ²⁾	Mass inertia of the motor
P 0463	MOT_PolePairs ²⁾	Number of pole pairs
P 0470	MOT_Rstat ²⁾	Stator resistance: The phase resistance is taken into account in the calculation.
P 0471	MOT_Lsig ²⁾	Stator inductance: The stator inductance is taken into account in the calculation.
P1530	SCD_SetMotor control	Start of calculation
¹⁾The parameters are only of informative nature, but should be set for a complete motor data set. ²⁾ The parameters are used for calculation of controller settings, and have a direct effect on the response of the servocontroller.
