• Additional Cooling System : Required if the engine is used in hot or high intensity environments.
• Monitoring Devices : For continuous monitoring of current and voltage during operation.

Mathematical Formulas for Optimal Use Parameters

To calculate the optimal parameters of engine use, consider:

• Electric Power: $P$
  • Where VV $V$ is the voltage (440 V for the armature) and II $I$ is the current (855 A). The absorbed power is P=440 V×855 A=376200 WP = 440 \text{ V} \times 855 \text{ A} = 376200 \text{ W} $P$ $=$ $440$ $\text{V}$ $\times$ $855$ $\text{A}$ $=$ $376200$ $\text{W}$ or 376.2 kW.
• Couple: $T$
  • Where PP $P$ is the power in Watts and ω\omega $\omega$ is the angular velocity in rad/s. Use engine speed to calculate torque in Newton-meters (Nm).
