Abstract:
This paper analyzes the torque characteristics of outer rotor PMG for low head hydro power application. The aim is to prevent the generator torque from exceeding the turbine torque as the prime mover so that the system can work properly in both start and steady state conditions. The PMG is of outer rotor type and the torques are calculated analytically and numerically. The analysis is focused only on the PMG without connecting it to the turbine. Two analyzed torques include electromagnetic torque and starting torque, which comprises cogging torque, hysteresis torque and friction torque. The el

This paper models the electromagnetic force/torque of a long-stroke magnetically levitated planar motor. Based on the Lorenz force volume integral law and the force/torque superposition principle of rigid body, the electromagnetic force/torque is modeled. Experimenting results indicate the model is consistent with the measured results in sine distribution and sine period, and the errors between the model values and the measured values originate mainly from the measurement system.

Industrial machines with sharp moving blades are extremely dangerous to workers. These machines often rotate for some time (called the run-down time) before completely stopping due to little or no brakes. In the case where brakes are used, they are mechanical in nature and are associated with problems of wear out and frequent maintenance among others. In this paper, we proposed a mathematical model and implementation of an electromagnet and design and construction of a mechanical support frame and a controller for the electromagnetic braking system.
