SEWEURODRIVE

The system represented consists of an electric motor and a gearbox. The calculator is designed to obtain the technical specifications at the output of the gearbox. To use this calculation tool, input data as detailed in the following protocol:

MOTOR: 

• Rotational Speed: Input the speed at which the motor rotates, expressed in revolutions per minute.
• Power: Input the power that the motor is capable of generating, specified in kilowatts.

From these inputs, the calculator will generate the Nominal Torque, which will display the nominal torque the motor can develop based on the input rotational speed and power.

GEARBOX:

Input information pertaining to the gearbox that will be connected to the motor.

• Transmission Ratio: Input the ratio of the gearbox’s input and output speeds.
• Efficiency: Input the gearbox’s capability to conserve power during transmission, expressed as a decimal value (for example, 0.80 for an efficiency of 80%).

OUTPUT: 

• Rotational Speed: The calculator will show the new output shaft speed after passing through the gearbox, based on the transmission ratio.
• Nominal Torque: Will show the torque available at the gearbox output, adjusted according to the efficiency input previously.
• Useful Power: Will display the effective power at the output, taking into account the losses associated with the efficiency of the gearbox.
