Answer:"Temperature rise" is an important parameter to measure and evaluate the degree of motor heating . It is measured under the thermal equilibrium state of the motor at rated load . The usual way for end customers to perceive the quality of a motor
Answer:the reduction ratio of the reduction motor refers to the rotation speed ratio between the reduction device and the rotor on the motor output shaft. The selection of the reduction ratio needs to be comprehensively considered based on the application r...
Answer:The basic structure of DC reduction motor is divided into two parts: stator and rotor. NOTE: Do not confuse commutator with commutator. (1) The stator includes: main magnetic pole, frame, commutation pole, brush device, etc. (2) The rot...
Answer:Brushless motors, including synchronous motors and asynchronous motors, are a type of motor with high efficiency, high reliability, low vibration, high efficiency, low noise, energy saving and consumption reduction. They can achieve fast response and...
Answer:In 2023, the micro motor industry is undergoing a series of changes. With the development of my country's micromotor industry and the improvement of technical level, the proportion of high value-added products continues to increase, so the overa...
Answer:the three-phase asynchronous motor loading methods include mechanical load, electrical load, inertia load, hydraulic load, etc. In terms of load regulation, various methods such as frequency conversion speed regulation, pulse width modulation speed r...
Answer:We know that whether the motor is too large or too small, abnormalities will occur. If the power of the motor is too small, a "small horse pulls a big cart" phenomenon will occur, causing the motor to be overloaded for a long time, causing its i
Answer:The permanent magnet motor uses permanent magnets to generate the magnetic field of the motor. It does not require an excitation coil or an excitation current. It has high efficiency and a simple structure. It is a good energy-saving motor. With the ...
Answer:The fixed part of the motor is called the stator, on which pairs of DC-excited stationary main magnetic poles are installed; while the rotating part (rotor-rotor) is called the armature core, on which the armature winding is installed. After being en...
Answer:DC geared motors are widely used in the machinery industry, mainly because of the excellent performance of the equipment. Everyone must protect the equipment during use. So how to prevent the device from being burned? An issue that many users are con...
