I am sorry for my bad english. I am from europe.
The motor is driving a winch. An abrubt stop can be an emergency stop (2 brakes: 1 at NDE of the motor and 1 at the drum of the winch.
2 motors are connected to 1 winch. Motors are driving in master slave configuration. (what happens for example...
We have following situation:
AC motor, 160kW, framesize 315, B5 flange-flange mounted to a gearbox.
Coupling on mototshaft with a key (DIN standard) coupled to gearbox by a spline to the gearbox (rigid coupling in my opinion)
On 1 motor we have suffered a DE bearing problem. bearing is...
Dear Cockroach,
Thanks for your calculations. It is similar to the DIN 6892 method
The DIN 6892 calculates in 2 ways; first a calculation with the equivalent torque and second with the maximum torque.
Next to this the DIN takes more external factors in consideration, for example the frequency...
Thanks for all response, more details from my side:
Nominal torque: 28650Nm
Application factor (Ka)1,5
Equivalent torque: 42975Nm (=Ka x Tnom)
Maximum torque: 85950Nm (= breakdown torque of AC motor (=2) x Ka)
Shaft end diameter 180mm
Key width: 45mm
Key height: 25mm
Key length: 290mm...
Dear all,
My question is the following:
I have to check the shaft-key connection of a 3000kW - 1000RPM asynchronous motor which is intend to drive a pump.
When I compare the shaftend diameter with other motors (similar torque) the shaft-end diameter is smaller. To be sure I want to check it...
