The LZ series down-hole motor include three categories according to their bit differential pressure ranges , namely 3.5MPa , 7.0MPa and 14.0MPa series ,For 3.5MPa motor ,the ratio of the rotor and stator lobes is on to tow (single lobe motor);for 7.0MPa motor, the ratio of the rotor and stator lobes is one to two or N to N+1 (single and mulitple lobes motor);and for 14.0MPa motor ,the ratio of the rotor and stator lobes is N to N+1 (multiple lobes motor).
