YZPSL、YZLNYP、YZLPWT、YZTPWTSeries of high-temperature-resistant water coolingThe motor is an internally circulating water-cooled variable frequency speed control three-phase asynchronous motor developed and designed by our factory based on the variable frequency speed control series of motors, tailored to the specific conditions of the metallurgical continuous casting machine. It is suitable for high-temperature environments and variable frequency speed control systems. Its features include a wide speed regulation range, stable operation, high reliability, high operating efficiency, and a novel and aesthetically pleasing design.
1.2 This series of motors features a unique cooling system that ensures stable operation under high ambient temperatures over long periods, with characteristics such as resistance to high temperatures and humidity, as well as corrosion resistance.
1.3 YZPSLE、YZLNYPEJ、YZWTEJSeries of water-cooled electromagnetic variable-frequency motors feature a friction dry brake added to the non-axial extension end of the water-cooled variable-frequency motor. The brake is divided into two types: power-off brake and power-on brake, among which the power-off brake operates at a working voltage ofDC170V and DC24V, when operating at DC170V, the external power supply is AC380V, the motor has an internal rectifier block operating at DC170V, and the external power supply is DC24V (supplied by the user).
1.4 This series of motors can operate continuously at variable speeds from 3 to 100 Hz. Within the range of 3 to 50 Hz, it operates at a constant torque; from 50 to 100 Hz, it operates at a constant power. The product is widely used in various mechanical equipment requiring continuous variable speed and frequent forward and reverse operations in high-temperature, high-humidity, and corrosion-resistant environments, such as metallurgy and chemical industries, and can be matched with various frequency conversion devices at home and abroad.
The stator windings of this series motor are insulated with H-class insulation and have a protection rating of IP55.
The 1.6 motor operates normally in locations with an altitude not exceeding 1000m and ambient air temperature not exceeding 60℃.
1.7 The cooling water pressure should not exceed 0.6 Mpa. The quality of the cooling water should be tap water, pure water, or industrial softened water, and it must be free of suspended particles. If there are impurities in the industrial softened water, they should be filtered before use. Ensure the water passage is clear during motor operation.
1.8 This series of motors features two water inlet and outlet pipe connections, with a 4-inch (1/2") diameter.
1.9 Motor Installation: During B5 installation, the pipe connection on the flange end cover should be positioned below as the inlet pipe, and the pipe connection on the rear cover should be positioned above as the outlet pipe. For vertical (V1) installation, water should enter from the flange end cover and exit from the rear cover. For inverted (V3) installation, water should enter from the rear cover and exit from the flange end.
