Special hydraulic motor is derived motor Y2 series motor, and hydraulic systems for supporting, while supporting the piston, vane pumps, gear pumps and other types of pumps, pump motor group composed. Low noise 1, Y2 motor exterior design, manufacturability, top or side outlet outlet, appearance, generous 2, electromagnetic design, according to the requirements of the hydraulic motor design with: Compared with the traditional pump motor has the following advantages. low temperature, high efficiency, efficiency in line with GB18613-2012 standard requirements; 3, in the structural design, the pump and motor with the Department, increasing fuel tank vent to prevent oil from entering the internal hydraulic motor to ensure the safe use and easy to disassemble the motor . 4, the use of direct-mode, reducing couplings, pump bracket, chassis and other components common to shorten the length of a quarter. With Direct mode, run more smoothly, less noise. And the pump can be replaced individually. Conditions of Use: Ambient temperature: -15 ℃ -40 ℃ no more than 1000 meters above sea level. Y2JD hydraulic motor for the main technical indicators 1, Voltage: Within 110-660V, 50-60HZ any voltage within the range; can be matched with the user exports. 2, the working system S1 Insulation class: B or Class F (Class H manufactured according to user requirements); 3, protection class IP44 / IP55; 4, cooling method: IC411; 5, Connection: 3KW and below rated power motor with Y Connection; 4KW and above rated power motor with Δ connection;
