In recent years, many works have appeared, which present novel mechanical designs, control strategies, or trajectory planning algorithms for improved energy efficiency. The actuator model is an ...

Water cooled feed throat, no hopper; and 250 HP, 500 V, 1750/2300 rpm DC motor through a reducer. Auxiliary equipments A typical pipe line needs some auxiliary equipment besides the extruder used for ...

The HF‑11 hypercar blends insane performance with innovation: 12,000 rpm flat-six or 850-hp EV — both in one car. Limited to 25 builds, starting at $1.85M.

This paper proposes a torque ripple reduction for brushless DC (BLDC) permanent magnetic (PM) motor drive based on the DC-link voltage pulse amplitude modulation (PAM). The proposed method improves ...
