Is the LdTrq input required in the Surface Mount PMSM block ?

3 views (last 30 days)
Hi everyone,
I am trying to implement FOC algorithm in Simulink using the Motor Control Blockset. I want to simulate the iPower Gimbal Motor GBM2804H-100T with the Surface mount PMSM block. However, I don't understand what the LdTrq input is or how to set it up. SInce it is a motor I do not understand why a motor shaft input torque is required. Also if I am required to use this input, could I use a constant or would I need to do something else ? Please any help would be really appreciated.

Ldtrq is the load torque on the motor, to simulate shaft behaviour this been considered. You can use constant block to simulate the constant load torque, For example if you would like to simulate no load condition use a contant block with zero as value.
