Determining Electric Motor Load and Efficiency

Determining Electric Motor Load and EfficiencyThe actual speed of the motor is less than its synchronous speed with the difference between the synchronous and actual speed referred to as slip. The amount of slip present is proportional to the load imposed upon the motor by the driven equipment (see Figure 4). For example, a motor running with a 50% load has a slip halfway

Crusher Graph Torque Speed

Crusher Graph Torque SpeedCrusher Graph Torque Speed. As the speed changes, the load torque remains constant and the horsepower changes linearly with speedonstant torque loads cause motors to draw relatively high current at low speeds when compared to variable torque appliionshis is why the same size drive may have a lower hp rating for constant torque appliions.

Using Tunnel Boring Machine Penetration Tests to Quantify ... · The penetration limit is a function of muck conveyance, bucket design, cutter wear and maximum head revolution speed (Frenzel et al., 2012). The torque limit provides the transition from the penetration limit to the maximum thrust (Frenzel et al., 2008), which is a function of the rotational speed and is controlled by the maximum torque capacity.
