THE ELEVATOR: FROM BASICS TO CALCULUS – Motor Control; Ropes and Traction; Traffic Analysis
Author: Dr. Albert So
Publication Date: 2019
This new book first provides a quick introductory review on elevator systems to help readers who have no background knowledge in elevator technology get into the world of elevators. It then leads to its three major parts: "Motor Drive and Control," "Ropes and Traction" and “Traffic Analysis.”
There are four chapters in each, which gradually increase in depth. This material is mainly for technical undergraduate/postgraduate students and professionals, as they are mainly mathematical. Having said that, the mathematics are only up to the level of simple calculus, involving differential equations of the second order. The rest is mainly high-school algebra and geometry. Detailed explanations help readers follow the derivation of all formulae.
Learning reinforcement questions and answers are also provided for each chapter.
