- Goal : to build a high torque system that is capable to self-regulate thermal dissipation through frictional heat to heat up test samples
I would like to design a system that is capable of generating frictional heat through its servo motor to heat up an enclosed chamber to 500 'Celsius . The challenge is that external heating source such as heating element, heat chamber etc. shall not be included in the design setup. Assuming that the rotor works at a speed of 1000 rpm, what is the torque needed so that the resulting frictional heat could heat the chamber from 30'Celsius to 500'Celsius?
I tried to make some simple calculations by correlating the three formulae below but the value I got doesn't really make any sense:
1) Continuous power (kW) = (2*pi*RPM*Torque)/60000
2) Power = Energy / time
3) Energy (thermal) = mass * specific heat capacity * temperature change
Did I calculate it correctly or it is not so straight forward?
