What Do Constant Torque and Constant HP Mean on an Electrical Motor Nameplate?

[Eng_Luqman]

I have This Electrical Motor Used For Slitting Machine Recoiler For Slitting up to 2.5 mm Steel Sheets Coil :

Specifications
Electrical Motor :

OutPut 110 Kw 150 HP 600 RPM

80 VOLTS 213 Amper

Constant Torque : 60 600 RPM
Constant HP : 550 1800 RPM

I want to know what are those meaning ... those datas I found it on the name plate of the electrical motor .

Specially The Both Of (( Constant Torque )) And (( Constant HP ))

The first time I observe this kind of specifications on a motor name plate

Please send me your help as you can

Regards

Thank you for reaching out and sharing your questions about the electrical motor used for the slitting machine recoiler. The specifications you have provided indicate that the motor has an output of 110 kW or 150 horsepower, with a rotation speed of 600 RPM. It operates at 80 volts and 213 amps.

To answer your question, both "constant torque" and "constant HP" refer to the motor's ability to maintain a consistent level of torque and horsepower respectively, regardless of the speed at which it is operating. This means that the motor can produce the same amount of force and power consistently, even if the speed changes. This is important for the operation of the slitting machine, as it requires a steady and reliable source of power to cut through the steel sheets.

I can understand that this may be the first time you have seen these specifications on a motor nameplate, but they are common in industrial applications where precise and consistent power is needed. I hope this explanation helps to clarify the meaning behind these terms and how they relate to the function of the motor in your slitting machine. If you have any further questions or need more assistance, please do not hesitate to reach out. Best of luck with your project!
