Dear experts;
In choosing a motor to run with a NI 9503 powered by +24V; my colleague has purchased a 3.5V stepper motor (datasheet attached). His feeling is that since power is applied for a fraction of a second, that the RMS power is within the limits of the motor.
To me it seems that the motor we choose should be rated for the applied voltage (IE. +24V).
Has anyone heard of this practice?
Here are the characteristics of the NI 9503:
Input/Output Characteristics
Motor DC power supply (Vsup).......+9 to +30 VDC
Minimum phase inductance..............1 mH
Maximum phase inductance .............20 mH
Type ..................................................PWM
PWM frequency................................ 20 kHz
Current per phase..............................3 A RMS
Thanks for your thoughts.
