Simulation and Experimental Verification of a HB-Type Vernier Motor
Journal Title: Engineering, Technology & Applied Science Research - Year 2013, Vol 3, Issue 1
Abstract
Direct drive motors are used as actuators in numerous applications in which they must rotate at low speeds with high torque and low torque ripple. Various types of vernier motors have been studied recently. The HB type vernier motor is one of them. Its rotor structure is the same as in a HB type stepping motor but has a field winding at the rotor and has multiphase windings in the stator. In the present work, a Matlab simulation of a HB type vernier motor is presented. To validate the motor results and response, the authors fabricated the motor and implemented its drive circuit. The motor was tested for different load conditions. Experimental results are found identical to simulation results and it is also shown that the motor has low torque ripple.

Variable Speed Limits: Strategies to Improve Safety and Traffic Parameters for a Bottleneck
The primary purpose of the speed limit system is to enforce reasonable and safe speed. To reduce secondary problems such as accidents and queuing, Variable Speed Limits (VSL) has been suggested. In this paper VSL is used...
Effect of Viscosity on the GTA Welds Bead Penetration in Relation with Surface Tension Elements
The aim of this paper is to study the effect of the viscous dissipation on the surface tension and its role on the shape of weld pool. Experiments were conducted on four different casts of ferritic stainless steel with d...
