How to calculate motor efficiency for variable-speed centrifugal pumps: knowing the efficiencies of the pump, VSD, and motor will enable the engineer to calculate the kW input for a pump, from minimum to maximum flow and head conditions for that pump. Here, the author goes through that ...
If the motor is not put into operation immediately upon arrival, it is important to protect it against external factors likemoisture, high temperature and impurities in order to avoid damage to the insulation. Before the motor is put into operation after a long period of storage, you have to ...

The inertia values of the motor, coupling, and pulleys are typically specified by their respective manufacturers. However, the inertia of the load must be calculated. Remember that the load includes the mass of both the external load and the belt, since the motor has to generate enough torque ...

In this comprehensive guide, we’ll explore the ins and outs of motor construction, design features, and the factors that can influence a motor’s performance and efficiency. Having a solid understanding of the design choices involved will equip you with the knowledge to pick the ideal motor fo...
If the motor has 100% efficiency all electrical power is converted to mechanical energy (Pin = Pout). However such motors do not exist. Even precision-made small industrial motors have a maximum efficiency of 50-60%. Fig. 1: Motor Power Closed-loop control using Rotary Torque Sensor and US...
Rotary Torque Transducer is also a crucial part of dynamometers (or dyno for short), as it provides torque measurement and angular speed (RPM) to easily calculate output power, allowing accurate calculation of motor or engine performance in Kw or HP as well as its electromechanical efficiency. ...
P.S. The way you're designing, the motor choice is constrained, you could also start with the motor you want to use and calculate the wheel size (or gear box etc.) from it's torque at optimal efficiency. Logged To be responsible, but never to let fear stop the imagination.diego...
Instead, when the crane's upward force precisely balances the weight of the load, a tension T (force per unit length) is preserved in the rope. The load moves upward when the motor drives T above this point, assuming the cable is strong enough to withstand the power. ...
