Product Description

Product Description:
 
            TYM series low-speed and high-torque permanent magnet direct-drive synchronous motor is a new type of permanent magnet direct-drive synchronous motor developed by our company for the market demand of low-speed and heavy-duty equipment. The rotor uses permanent magnet excitation to realize power transmission of low-speed and high-torque. The motor is controlled by frequency converter. In the application of mill, the reducer is removed. Direct drive small gear. It has the advantages of compact structure, high starting torque, high efficiency, stable operation, high reliability, low noise and convenient installation, and basically realizes maintenance-free. The change of transmission mode, the removal of reducer, simplifies the transmission chain of mill, reduces the maintenance cost of reducer, removes the intermediate link, and improves the overall transmission of mill. Efficiency.

          This series of permanent magnet motors are magnetized by permanent magnet materials. Compared with traditional current-excited motors, the power factor is significantly increased, the stator current and stator resistance losses are reduced, and the rotor copper loss is not found in stable operation. High efficiency and power factor can be maintained in the rated load range of 25%-120%. The energy saving effect of light load operation is more significant. Compared with the characteristics of efficiency, power factor and load ratio of permanent magnet motor and asynchronous motor, they have obvious advantages.

         TPYM series low-speed, high-torque permanent magnet direct drive frequency conversion motors are used in all power transmission equipment which need to provide low-speed, high-torque and high-power in the industrial field, especially in the grinding machinery equipment of our country. Based on the unique electromagnetic characteristics and vector control method of permanent magnet motor, the characteristics of power supply and the system price ratio, a set of drive and control system solutions are developed to optimize the motor design, reduce the material cost and reduce the power loss. Produce remarkable economic benefits. Eliminate the mechanical deceleration device, greatly reduce the maintenance workload of equipment, at the same time enhance the reliability and sustainability of motor operation from the design, reduce the maintenance cost after putting into operation.

Main classification	DC Motor is a machine that converts mechanical energy into DC power. It is mainly used as DC motor for DC motor, electrolysis, electroplating, smelting, charging and excitation power supply of alternator. Although in places where DC power is needed, AC power rectifier is also used to convert AC into DC power, but from some aspects of performance, AC rectifier power supply can not completely replace DC generator.
Application	DC motors are widely used in tape recorders, video recorders, video discs, electric shavers, hair dryers, electronic watches, toys and so on.
Maintenance method	Professional motor maintenance center motor maintenance process: cleaning stator and rotor - replacing carbon brush or other parts - vacuum F pressure dipping paint - drying - Calibration balance. 1. Use environment should be always dry, motor surface should be kept clean, air intake should not be hindered by dust, fibers and other obstacles. 2. When the thermal protection of the motor continues to operate, it should be ascertained whether the fault comes from the motor or the overload or the setting value of the protective device is too low. After eliminating the fault, it can be put into operation. 3, ensure that the motor is well lubricated during operation. The general motor runs for about 5000 hours, that is to say, lubricating grease should be added or replaced. When bearing overheating or lubricating deterioration is found in operation, the hydraulic pressure should change lubricating grease in time. When replacing grease, the old grease should be removed, and the oil groove of bearing and bearing cover should be washed with gasoline. Then ZL-3 lithium grease should be filled with 1/2 (2 poles) and 2/3 (4 poles, 6 poles and 8 poles) of the cavity between the inner and outer rings of the bearing. 4. When the life of the bearing is over, the vibration and noise of the motor will increase obviously. When the radial clearance of the bearing reaches the following value, the bearing should be replaced. 5, when removing the motor, it is OK to remove the rotor from the shaft extension or the non extension end. If it is not necessary to unload the fan, it is more convenient to take out the rotor from the non-axle extension end. When pulling out the rotor from the stator, the stator winding or insulation should be prevented from being damaged. 6. When replacing the windings, the form, size, turns and gauges of the original windings must be recorded. When these data are lost, they should be obtained from the manufacturer and the original designed windings should be changed at will, which often deteriorates one or several performance of the motor or even makes it impossible to use them.
