“…Low dynamic stiffness K d leads to poor disturbance rejection and sensitivity to load variation [11]. On the other hand, the equivalent electric circuit for the proposed motor can be represented by (9), where e and K E are the voltage supplied to the stator winding and back-EMF coefficient, respectively, i a is the coil current, z d is the displacement of the mover, L and R are the winding inductance and resistance of the proposed motor, respectively [11][12][13][14][15].…”

This paper deduces from Finite-Element Analysis (FEA), the influence of leading design parameters on the performance of a novel T-shaped permanent magnet (PM), quasi-Halbach magnetized tubular linear motor. The proposed motor is designed and developed for small reciprocating applications. In order to obtain the maximum power density, a two-dimensional Finite-Element model is developed to investigate the performance of the proposed machine. The proposed T-shaped PM structure has a higher power density as compared to the conventional rectangular-shaped PM structure. The losses of the motor, such as copper loss and iron loss, as well as the efficiency, are established as functions of a set of motor leading design parameters. It is shown that the developed motor produce satisfactory output power, around 85 W, which is enough to operate the direct-drive reciprocating compressor of a household refrigerator.

“…LOA with slotless stator having multiple stator poles is presented in Jang et al (2004), where cylindrical Halbach array configuration is used with the radial magnetization of PMs in the form of arc segments. The impact of mechanical resonance on the dynamic performance of the system is also investigated in Jang et al (2005). LOA with slotted stator structure having single-coil is presented in Mizuno et al (2005) which is designed by permeance method and finite element method (FEM).…”

Purpose For compactness and ease in assembling, a novel miniature size tubular moving magnet linear oscillating actuator (MT-MMLOA) design for miniature linear compressor application is proposed in this paper. Design/methodology/approach This MT-MMLOA design possesses a modular C-core stator structure having separation at the middle. Axially magnetized tubular permanent magnets are accommodated on the mover. To improve the output parameters of the linear oscillating actuators (LOA), all the design parameters are optimized using a parametric sweep. Finite element analysis of the proposed design is performed to examine the magnetic flux density as well as thrust force under both static and dynamic analysis within the intended stroke range. Findings Compared to conventional LOA for miniature compressors, the motor constant of the proposed LOA is 37 N/A that is 85% greater while keeping the same size of LOA. Permanent magnet volume used in the investigated topology of LOA is 26% reduced. Additionally, the overall volume of the machine is 10.3% decreased. Furthermore, the proposed topology is simple, inexpensive and easy to manufacture. Originality/value Electromagnetic performance comparison with different topologies proposed earlier in literature is carried out to prove the performance superiority of the proposed design.
