“…The motor stator coil is made of copper wire which causes a great thermal loss when inputting much current. In order to get a high magnetic flux density, rare earth magnets are used in rotor part, achieved via magnetic access and electromagnetic analysis [3][4][5]. For stator part, in order to generate small torque ripple, designs of the optimal number of slots and configuration of rotor magnetic poles are used, with finite element method, to build a correspondent mechanical process with materials that fit the electromechanical silicon steel sheet.…”

Swivel spindle head is a key component used in five-axis machine tool of high performance and is of great importance in application and design. Nowadays, more and more components are manufactured by high performance multi-axis CNC machine tools, such as components of spaceflight, renewable energy and automobile, etc. Therefore, high performance machine tools of multiple axes are more and more urgently demanded, while Swivel spindle head is one of the most important components for a multi-axis machine tool. Hence, Swivel spindle head is one of the key to developers multi-axis machine tool . The study explores the highly responsive direct-driving motor able to drive the spindle head to rotate with multi-driving rotary technology. The dual-driving motor rotates via multi-driving units, generates torsion that magnifies and eliminates its clearance, and then drives the spindle head to rotate. Results of the test show that the completed machine tool can meet the standards of dual axis rotary head with high preformation in, no matter, speed, distance, positional accuracy, repeated accuracy or maximum torque, etc.

“…However, the inset PMSM is mainly utilized for medium to large size applications rather than small size ones due to the difficulty of manufacturing it. Hwang et al [7] made the smallest inset motor with an external diameter of 78 mm and a length of 50 mm. The rotor had a particular slot shape design for magnet retention and ease of assembly.…”

This paper presents the world’s smallest inset permanent magnet synchronous motor (PMSM) with a soft magnetic composite (SMC) core, providing ease of manufacturing for micromachine applications without silicon steel laminations. The inset motor can offer an additional reluctance torque and higher torque density with a lower usage amount of permanent magnet. A 15 mm diameter inset motor was developed with the thickness of a tile-type permanent magnet which is limited to 1 mm by the manufacturer. The motor was designed with high torque density and low torque ripple by varying the interpole iron width for the rotor. Two inset motors were made using both SMC and silicon steel materials for comparison. The performance of the SMC motor was inferior to the silicon steel motor, but it still meets the specifications of the commercial market. If the thickness of the tile-type permanent magnet is further reduced, the micro inset motor with a SMC core can be easily mass-manufactured using powder sintering.
