Servo Motors Rated Speed

Servo Motors Rated Speed

Servo Motors Rated Speed

(OP)
Hi Everyone,

What is the difference between "Rated speed nC(1/min)" and "output speed" in servo motors.

At the same time While "rated motor speed" is 1405(1/min) in gearbox catalogue, Rated speed is 3000 (1/min) in servo motor catalogue for the same gearbox.

If someone has a knowledge about this kind of servo motor and gearbox, can you inform to me.

Thanks in advance

RE: Servo Motors Rated Speed

I would think that nC 1405 (1/min) is "max" speed at max torque, while nN 3000(1/min) is max speed for motor continuous with "medium" torque.

IC [A] - maximum short-time permissible current (r.m.s. value) which is given by the intersection of current limitation of the servomotor and of limitation by the rated voltage of the converter – LIMITING POINT C; mostly IC is identical with the highest permissible servomotor current (Imax.)
MC [Nm]- maximum torque of the servomotor at the current IC and speed nC
nC [min] - speed of the servomotor at IC and MC

MN [Nm] - rated torque - continuous torque on the servomotor shaft at nN and UN for continuous running duty S1 (defined for temperature rise of the winding 105 K and for the rated value of KE)
IN [A] - rated current - r.m.s. value of the servomotor current for MN and nN
nN [min-1] - rated servomotor speed
