The eccentric rotating mass vibration motor (erm) is also popularly called as what?

Given the following experimental data collected, what is the approximate torque of this motor at peak efficiency?

Deseribe the constructional features and characteristics, of a d.c motor that would be used in elevators. Identify another application for this motor?

A block with a weight of 5 kg hanging from the ceiling attached to a spring is raised and then pulled downward. As it passes downward through the spring's unstretched position it has a speed of 10 m/s downward. If the spring has a stiffness of 5 N/m, determine the maximum position below the spring's unstretched position achieved by the block.
