YZP column lifting special frequency speed control three-phase asynchronous motor, is the company summarizes the successful experience of frequency speed control three-phase asynchronous motor, and the development of crane special frequency speed control three-phase asynchronous motor. It has fully absorbed the advanced technology of frequency conversion and speed regulation at home and abroad in recent years, and is especially suitable for the requirements of high starting torque and frequent starting of cranes. It can be matched with various frequency conversion devices at home and abroad to form an AC speed control system with high precision and high dynamic performance. The basic technical requirements of the motor are in accordance with IEC34-1 and GB755 international and national standards, and the installation dimensions are in accordance with IEC72 international standards.
Product performance :
1. The frequency conversion range of the motor is from 1 to 100 Hz, of which 1 to 50 Hz is constant torque speed control and 50 to 100 Hz is constant power speed control (50 to 70 for H450-4 and above).
2. The insulation class of the motor is F class, or H class according to the requirements of users. 
3. The motor has good low-speed performance, smooth torque in low-frequency operation and no creeping phenomenon. 
4. Strong overload capacity, rated voltage, rated frequency, can withstand 2 times the rated torque for 1min. 5. Good low-speed starting performance, low-frequency starting torque can reach 150% of the rated torque. 6.
 6. According to the requirements of the user can be with a variety of high resolution sensors (photoelectric encoder, speed generator, overspeed switch, etc.) can be with electromagnetic brake, gear reducer and other accessories.
