High starting efficiency for hydraulic
motors
Whereas many hydraulic motors display starting torque characteristics as low as 60% theoretical, recent in house testing of GM Series hydraulic motors consistently returned results better than 90%.
Whereas many hydraulic motors display starting torque characteristics as low as 60% theoretical, recent in house testing at the manufacturing base of SAI in Italy, confirmed that the latest version of the GM Series hydraulic motors, distributed in the UK by SAI (GB) consistently returned results better than 90% The tests, which were carried out at the request of a new potential customer, pitted the SAI 300cm3 motor, head to head, with one of a similar capacity, produced by possibly the best known hydraulic motor manufacturer

Hydraulic motors run past 3000rev/min
The BD series of dual displacement radial piston hydraulic motors satisfy demands for high-speed performance combined with low-speed controllability and high starting torque efficiency.
The SAI figure at start was as stated above, whereas that of the competitor was just 65%.
In future, SAI has become the first choice of this particular customer.
This remarkable performance is mainly due to the innovative use of roller bearings in the area where most suffer highest losses, namely the eccentric area of the crankshaft.
A further inherent ability of the design allows the Motors to be run under negative pressure situations and in virtual free wheel conditions.
With a vast range of displacements available from 40 to 12,000cm3/rev, the SAI range of hydraulic motors must be considered as one of the most versatile and economic available on today's UK hydraulic motor market.
