Product Description
Overview of products
DMP series motor with inverter device can realize stepless speed regulation, which is based on DM series three-phase asynchronous motor by Self-research and development, and can reach energy saving and automatic control.
Features and Advantages
DMP series motor features High efficiency, wide speed range, high accuracy, stable operation, easy operation and maintenance. And mounting dimension comply with IEC standard.
The working mode is continuous operation(S1)
1,CAD technology has been applied into the motor design. In order to adapt the motor to SPWM and PWM fed by variable-frequency power, slot form of stator and rotor, and stator winding distribution are taken into consideration to obtain a suitable inductance value to suppress and reduce the negative effect caused by harmonics.
2,The margin is taken into consideration when electromagnetic load of the motor is designed, which can not only ensure overload capacity of motor at high-frequency operation but also keep constant torque output in low-frequency operation. The features of the motor is the strong overload capacity and it can withstand 150%overload of rated torque for one minute. And the motor features the excellent performance at the low-speed .It has smooth torque at a low-speed operation and the-motor runs without creeping. Furthermore, insulation system of motor is the insulation class F widely used by international community, which is reliable and whose performance is excellent. For design, mounting dimension of the motor is the same as DM series of motor, which is convenient for clients to select
3,The motor adopts independent ventilated cooling structure. Axial independent cooling fan is located at the non-shaft extension side. The motor features high efficiently, low noise, simple structure and the motor is suitable to fit auxiliary equipment such as the encoder, tachometer, and brake, etc., which assure that the temperature rise if motor at a low speed operation will not exceed limited value.
The main technical data
1. Rated voltage:380V
2. Rated frequency:50Hz
3. The type of cooling: IC416
4. Under the condition of U/F, constant-torque speed regulation is form 3 to 50Hz and constant-power speed regulation is from 50-100Hz.
5. Insulation class: F
6. The degree of protection for enclosure is IP54, also can be made into IP55.
7. The motor is Y connection for 3KW and below whereas delta connection for 4KW and above.
8. Accessories can be added as required, such as encoder, brake, temperature measurer, thermal protection, etc. See sample for type selection.
Main application areas
DMP series motor has been applied in transmission devices of speed regulation, such as steel rolling, crane, transportation, machine, printing and dyeing, paper-making, chemical, textile, medicine, etc. It matches with different inverter device. It with high precision sensor can realize close-loop operation.
