มอเตอร์ 2 Speed Hydraulic Variable Displacement Sai BD (BD1 BD2 BD3 BD5 BD)

2-speed Hydraulic Variable Displacement BD1 BD2 BD3 BD5 BD6 SAI BD motor
The BD series of products consists of items that are available in sizes from 1 to 6, being characterized by slide bearings and an extremely low friction coefficient. The very high starting torque efficiency and the mechanical efficiencies that are higher than average are other important features worth mentioning, and are applicable in both low and high displacement models. The motors are capable of working at low speeds with a high degree of speed stability, with the minimum stable speed depending on the motor displacement.

The output torque remains very constant and does not fall away at very low speeds, under start or stall conditions. The change of the motor displacement is achieved by changing the crankshaft stroke, at a pressure between 20 and 30bar. The change from high to low displacement or from low to high can take place dynamically.
