Answer:According to the data, the synchronous reluctance motor works by using the torque generated by the uneven reluctance of the rotor. The rotor is composed of ferromagnetic materials and non-ferromagnetic materials. It has no permanent magnets and no wi...
Answer:The alignment of the coupling is also called the alignment. After the pump and the motor are installed, the last task is to find the concentricity between the pump and the motor, that is, to make the axis of the pump and the prime mover on the same s...
Answer:The inverter is a device that converts DC power (battery, storage battery) into AC power (generally 220V, 50Hz sine wave). It consists of inverter bridge, control logic and filter circuit. Widely used in air conditioners, home theaters, electric grin...
Answer:The motor is a component that converts battery electrical energy into mechanical energy and drives the wheels of an electric vehicle to rotate.
Answer:A permanent magnet (PM) motor is an AC motor that uses magnets embedded or attached to the surface of the motor rotor. Electric vehicles use permanent magnet synchronous motors with high torque density and high efficiency. The magnets used are neodym...
Answer:The high-end development of new energy vehicles, the pursuit of stronger power, put forward higher requirements for acceleration from 100 kilometers. In particular, some high-end models are selling well, and the power index has become the focus of co...
Answer:The stepper motor is an open-loop control element stepper motor that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequenc...
Answer:The use of permanent magnet motors in combination with variable frequency drives is not new, and design engineers and equipment owners are beginning to choose more permanent magnet motor solutions for fan and pump application installations because th...
Answer:Motor type, soft start method, selection steps, damage causes and treatment methods, the difference between good and bad motors... All these problems are important reflections of the motor happiness index.
Answer:Switched reluctance motor ( SR for short ) was born 160 years ago, but it has been considered as a motor with low performance for a long period of time, so it is only used in a few small power places. In the early 1970s, Ford Motor Company of the Uni...
