Bookmark or Share- How are current and voltage related to torque and speed of a brushless ...All you have to think about is the power rating and nominal voltage. If the voltage you apply is high (must be within the voltage range) then it can take less current and less torque which indeed can be found out from the speed-torque curve for a fixed voltage. Voltage is proportional to speed, and torque is proportional to the current.
- How much voltage/current is "dangerous"?High voltage guarding. Assemblies operating at potentials in excess of 500 volts should be completely enclosed from the remainder of the assembly and equipped with non-bypassable interlocks. MIL-STD-1472G adds the following in Section 5.7.9.1.1: General background [...] All electrical systems of 30 volts or more are potential shock hazards.
- High Current or High Voltage that damages components?When the voltage across an insulator gets too high, it is possible that the insulator will stop insulating and will instead start letting some current through. This current flow can cause damage. If voltages are high enough, dielectric breakdown can result in arcing, which can cause heating, pitting, etc.
- High voltages vs. Energy loss - Electrical Engineering Stack ExchangeThe "top line" Voltage is the I x R voltage drop in the line and the bottom line Voltage is the transmission voltage. So loss ratio is effectively resistive_voltage_drop / line_Voltage. So, for a given conductor of resistance R the percentage of power lost will increase as current increases and will decrease as voltage increases.
- How is it possible to have high voltage and low current? It seems to ...The issue seems to be how we are first taught about a direct relationship between voltage and current (that is, an increase in voltage renders an increase in current if resistance remains the same) and then we're taught about power lines that have high voltage and low current (because other wise we would need thick wires that carry high current ...
