D.C. Motor Torque/Speed Curve Tutorial:::Understanding ...

By substituting equations 3. and 4. (torque and speed, section 2.1) into equation 2. (power, section 1.3 ), we see that the power curves for a D.C. motor with respect to both speed and torque are quadratics, as shown in equations 5. and 6. From these equations, we again find that maximum output power occurs at = ½, and = ½ repectively.

This crusher works on the simple mechanism called crank and slotted lever mechanism. When the motor is excited using a power source (i.e.3-phase power supply in this case) the shaft starts to rotate which in turn rotates the pulley which is connected to the motor by means of a belt drive. This pulley gives rotary motion to the transmission

Angular Motion - Power and Torque

An electric motor runs with 3600 rpm with an measured power consumption of 2000 W. The torque created by the motor (without losses) can be calculated by rearranging (1) to. T = 30 P / (π n rpm) = 30 (2000 W) / (π (3600 rpm)) = 5.3 Nm. Torque Calculator. P - power (W) n m - rotations (rpm) Download and print Motor - Torque vs. Power and rpm chart

Determining Electric Motor Load and Efficiency

Reasons to Determine Motor Loading Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor 's efficiency tends to decrease dramatically below about 50% load.
