At present, the majority of deep borehole drilling rigs at home and abroad still utilize Asynchronous Motors (AM) with variable-frequency drive as the main power component, which cannot achieve stepless-speed adjustment without decelerating mechanism. In addition, the expenditure of lubrication and maintenance are usually high, and the transmission efficiency is not very ideal. Therefore, this paper proposes a permanent magnet electric direct-drive deep borehole drilling rig (DBZJ40-Z), which firstly adopts Permanent Magnet Synchronous Motor (PMSM) with variable frequency technique to achieve stepless-speed control and direct-drive method to remove the transmission mechanism. Owing to the higher power factor and efficiency of PMSMs, this new type of drilling rig proposed is more energy efficient than the conventional ones equipped with AMs. Furthermore, the utilization of direct-drive mechanism replaces the intermediate transmission gearbox to save a lot of cost of maintenance greatly. Advantages of this new deep borehole drilling rig equipped with PMSMs such as saving energy, easy to maintain and operate, etc. had been verified in several practical applications. Practices proved that this sort of permanent magnet electric direct-drive deep borehole drilling rig equipped with PMSMs must be the future for conventional ones.

Mode transition is capable of improving the economy of hybrid electric vehicles but may also cause potential crises. When the hybrid power system (hybrid powertrain-HPT) has just completed the mode conversion, the driving system parameters change more dramatically, and the engine torque is fully transferred to the driving motor. Owing to the electromechanical coupling characteristics, HPT may be severely impacted during the operation, causing the instability of initial hybrid drive mode. To solve this problem, the mathematical model of the initial hybrid drive model for a series-parallel hybrid electric vehicle (SPHEV) is constructed. The local stability condition and bifurcation condition were derived to analyse the influence of engine throttle opening, and the instability threshold of the HPT was given. Moreover, an instability control methodology was designed to optimise the operating region of HPT for the initial hybrid drive mode, and vehicle tests of mode transition were carried out based on the existing SPHEV platform. Studies indicate that different throttle opening may lead to changes in bifurcation characteristics, causing the system to exhibit nonlinear behaviour and random oscillations. In addition, the control methodology proposed in this study can improve the stable operating region by 37% and restrain the oscillations of HPT.
