This simulation provides a scenario with a universal motor, axles for the motor, a blender jug, and a cooler. Due to the characteristics of the motor, it needs a minimum load or torque, as it could otherwise reach speeds that are so high (mathematically infinite) that they would cause the motor to blow. You will need to verify the relation between torque and speed. You can perform the mathematical analysis on the behavior of the motor by applying the concept of limits when the motor has one torque close to zero and another at infinity.
