Abstract
The simulation and optimization of a direct drive rotary motor (DDRM) for optimized torque output has been designed in this paper, which presents higher efficiency and better torque-to-volume ratio. Lacking of enough torque and precision, the traditional angular displacement control system is typically composed of a rotary motor and a moving platform from a series of complex mechanical transformations. The DDRM is an ideal alternative, deriving from the linear permanent magnetic motor, which features large torque, high precision, efficiency and it can be controlled directly and independently. Thus, to improve the output torque and the output volume ratio, this paper models the DDRM based on the finite element method (FEM) and presents the optimization procedures analytically. The simulation results show that torque output and the torque output volume ratio can be increased by 0.4 Nm and 12% respectively.
