Minimum voltage supplied to motor windings

[PhysicsTest]

TL;DR

Require clarification of minimum voltage to motor windings

I have seen the following specifications in the Hurst motor data sheet.

i have confusion on the Minimum DC voltage to the motor windings. It says as 10Vdc, but even if i give less than 10V it should not damage the motor windings. I can understand the upper voltage if i cross it may damage the windings, but why minimum voltage? Please help.

It may be that there is some condition that you have not specified.
Can you please provide the model number and a link to the source of the data.

That's an odd format for a data sheet. Real motor data sheets should have more detail, like torque curves, winding resistance and inductance, etc. It looks more like a description to me. Maybe they are saying it isn't a good choice if your application doesn't have at least 10V?

I have attached the data sheet.

It appears that those specifications are for the External Control Module that is an option for use with the motor. "The module is compatible with external motor drives using a 10 to 48Vdc power supply"

I have attached the data sheet.

Notice at the top of page 2 it says "Sample Motor Data Sheet". You want the real motor data sheet for your PN.

Try starting here, or contact the manufacturer if you can't find it online.

Anyway, the answer to your original question is you can ignore it, I think.

The motor it is an induction motor of 60Hz 2poles[3600 rpm]20 V 180 W rated[according to a table attached].
The supply voltage it is from an inverter. The input of the inverter is from 10 to 48 V d.c. and the output 20V [rms] three phases].
The inverter could maintain the output voltage if the input voltage would be not less than 10V but not more than 48 V d.c.
