Compact hydrostatic variable speed drives are supplied offered by khoday hydraulics and these variable speed drives are are manufactured by var-spe of italy. The hydrostatic operation is a combination of a hydraulic pump and a motor, which provides a high starting torque at 0 rpm, ideal for frequent start-stop cycles while getting away from peak current required by an electric motor at start. Built-in torque limiting valve, either preset or adjustable, helps preventing mechanical damage in case of accidental and sudden stops. These variable speed drives are ideal drives, for bad conditions like, vibrations or aggressive or dangerous or poorly ventilated environments. They are suitable for ambient conditions, which require water or dustproof construction. Constant low-speed with continuous duty is possible.Some of the technical features are provided by these drives which include: pprecision variators are available from 0.25 to 22 kw in many sizes. Drives are available with/without the standard electric motor. There are three different output speed range, available according to the different hp input to the variator, with the standard input speed of the electric motor at 1450 rpm, at all times. High starting torques are equal to 2 to 3 times nominal, for frequent starts or reversals and continuous work at low speeds, even under load, with even high torques than nominal. These are ideal drives, for bad conditions like, vibrations or aggressive or dangerous or poorly ventilated environments. They are suitable for ambient conditions, which require water or dustproof construction. Constant low-speed with continuous duty is possible.
