yes, Yang

                no need for controls, but motors must be 2 speed 5/20 m/min. with about 2.0 kw low speed and 3 kw for high speed. please send detailed specifications.

 

                        thank you

Dear peter kirolos

Your double girder overhead crane capacity is 10ton, span is 21meter, end truck length is 3.6 to 4.0 meters, speed is 2 speed 5/20m/min. After our engineers calculation, the maximum power of the motor only needs 2*1.1kw, but your request is 2 * 3kw. This will increase costs, resulting in power waste.

In addition, the speed you request is 5/20m/min, the motor power should be 0.8/3.0kw, not 2/3kw, and this is not in line with theory.

Anyway, I give you the power 0.8/3.0kw end truck price is 4900US$/pair, the detailed specifications as following;

Rated power (Kw):0.8/3kw

Rated current (A):4.79/6.28A

Effectiveness: 52.5%/79.4%

Power factor: 0.48/0.91

Locked-rotor current/Rated current=2.5/6.5

Locked-rotor Torque/Rated Torque=1.5/1.5

Breakdown torque/Rated torque=1.8/1.8

For the previous quotation, 2*1.1kw.

It is a variable frequency motor, 5/20m/min speed through the inverter, more efficient.

Best regards

Yang

yes Yang,

               I'm not an engineer my self, most likely your engineers calculations are more accurate, so far I'm getting information's off maintenance teck. I will get you more specific and accurate information's so we get this deal going. 

 

                                            thank you for your help.
