When selecting the torque motor, it is mainly the matching of its speed, the speed conference causes energy waste, and the speed is small without moving the mechanical operation, so we need to select the torque motor speed according to the requirements of the production machinery, and ensure that the motor matches the speed of the equipment when purchasing.

       Generally speaking, whether it is a three-phase asynchronous motor,Torque motorSuch as some motor products, its speed will not be lower than500r/minBecause when the power is certain, the lower the speed of the motor, the larger the size, the more expensive the price, and the efficiency is lower, such as the selection of high speed motor, is bound to increase the transmission ratio of the mechanical deceleration mechanism, resulting in the mechanical transmission part of the complex.

       For some high and medium speed machinery that does not need speed regulation, such as pumps, blowers, air compressors, etc., the corresponding speed motor can be selected to drive directly without mechanical deceleration mechanism. For machinery that needs speed regulation, the highest speed should be compatible with the speed of the production machinery. If the DC variable speed motor with changing excitation is used, the base speed of adjusting magnetic speed should be selected in order to make full use of the motor capacity.

       For example, some rolling machinery, elevator, etc., the working speed is low, often in a frequent positive and reverse operation state, in order to shorten the positive and reverse excessive time, improve production efficiency, reduce consumption, and reduce noise, save investment, choose the appropriate low-speed motor, the use of direct transmission without reducer is more reasonable.

       We usually applyTorque motorMostly selection4very1500r/minBecause this rated speed motor has a wide range of adaptation, and its power factor and work efficiency are also high.

       From the point of view of motor manufacturing, the higher the rated speed of the same power motor, the smaller the overall size, the lower the cost and the lighter the weight. If the higher the speed of the motor can be selected, the better the economy, but if the speed difference between the motor and the machine being dragged is too large, the more the transmission series of the deceleration device need to be installed, which will increase the cost of equipment and the energy loss of the transmission. Therefore, it is necessary to choose the best after analysis and comparison.
