In Part I we explored various motor technologies used today for industrial and traction motor design. Here in Part II we will explore another motor option: reluctance motors.
Lower-cost motor technologies exist that can be an attractive alternative to neo-based BL PM motors - and are not subject to unpredictable supply chains
Enhancing Safety, Quality, Delivery and Cost.
Synchronous drives are especially well-suited for low-speed, high-torque applications. Their positive driving nature prevents potential slippage associated with V-belt drives, and even allows significantly greater torque carrying capability. Small pitch synchronous drives operating at speeds of 50 ft/min (0.25 m/s) or less are considered to be low-speed. Care should be taken in the drive selection process as stall and peak torques can sometimes be very high. While intermittent peak torques can often be carried by synchronous drives without special considerations, high cyclic peak torque loading should be carefully reviewed.
There are few things in this world that elicit such a gleeful, childlike sense of wonder as does the word âÂ€œhoverboardâÂ€Âť.
There are three major types of reluctance motors: all three reluctance motors are non-permanent magnet, brushless motors. They are synchronous motors with a non-linear relationship between torque and current. The variable-reluctance step and switched-reluctance motors utilize the principle of magnetic attraction by inducing magnet poles within the soft-iron rotor, and by energizing a set of coils wound around stator teeth resident in the laminated stator. These two reluctance motors must be sequentially excited to achieve continuous, steady-state rotation. The design of all reluctance motors requires finite element analysis (FEA) software.
A discussion of the basics in DC drives, DC motors, AC drives, AC motors and synchronous motors.
Synchronous motors controlled by variable speed drives are bringing higher efficiencies to industrial applications.
If youâÂ€™re replacing your belts more than once per year, itâÂ€™s time to analyze your drive. From belt crimping damage to high belt installation tension to sprocket misalignment and adverse environmental conditions, this guide walks you through how to identify the reasons behind premature failure and makes recommendations on corrective and preventive measures.
