[Moved] DC Servo Motors behaviour at stall condition??

[Harry Mughal]

Hi all,
i need to provide a reactional torque to my hand by using a dc servo motor in current control mode. however i am just wondering what would happen to dc motor at stall torque?? i mean if i put my hand on the shaft and resist the generated torque by motor. At the same time if i control the current to the dc motor, will i be able to feel the corresponding changes in generated torque, will it be safe for motor.?? Actually em new at motors so need guidence from u guys. Regards!

Hi,

Most power loss (temperature rise) of a motor is caused by the motor current.
Therefore in most cases you are safe as long as the motor current is below it's rated current.
(If you use pulsed current, then you need to know RMS current instead of average current)

you will feel the torque generated.

"is safe or not for the motor?"

As KlausST has noted ,
you must supply the motor within the rated current.
