Protection Class:
Standard motor can fit for IP40,According for your need ,we can supply IP65.

Work Duty:
Our standard work duty is S1(Continuous)
You can pick S2,or S3.

Torque calculate: T=9.55*P2/n
Explain:
T:torque.P2:output power.
n: speed

Calculation of the motor winding temperature rise: θ=(R2-R1)*(234.5+T1)/R1-(T2-T1)
Explain:
θ:Temperature rise
R2:The thermal resistance when temerature rise stop.
T1:Ambient temperature when the test is beginning.
T2:Ambient temperature when the test is finished.
