摘要： A shaft (40) for use on in a mud pump having a shaft portion (42) and a hub portion (44) integrally formed with the shaft portion (42). The hub portion (44) extends radially outwardly of the shaft portion (42). The shaft portion (42) and the hub portion (44) are machined from a single steel blank. The hub portion (44) has an end face (50) with a plurality of bolt holes (52) formed therein. The hub portion (44) is attached to a sheave so as to receive the drive belt of a motor.

摘要： A moisture detecting system (40) has a power semiconductor module having a gate driver (62) with the gate in which the gate driver has an on condition and an off condition, a power supply (42) connected to the gate driver so as to supply voltage to the gate driver, a controller (46) cooperative between the power supply and the gate driver so as to set the gate driver between the on condition and the off condition, and a sensor (60) connected to the gate driver so as to detect a leakage of current across the gate driver. The controller is cooperative at the power supply so as to turn off the power supply when the signal is indicative of the leakage of current. The gate driver can an IGBT or a MOSFET.

摘要： A direct drive drawworks (100) has a permanent magnet motor (40), a shaft (41) extending from the permanent magnet motor (40) so that the permanent magnet motor directly rotates the shaft (41), and a drum (43) connected to the shaft (41) away from the permanent magnet motor (40) such that the rotation of the shaft causes a corresponding rotation of the drum. The permanent magnet motor (40) has a housing (42), a stator (62) positioned in the housing, and a rotor (64) cooperative with the stator. The rotor (64) has a drive plate (66) affixed thereto. The shaft (41) is directly connected to the drive plate (66). A bearing housing (45) rotatably supports the shaft.
摘要翻译：直驱动绞车（100）具有永磁电动机（40），从永磁电动机（40）延伸的轴（41），使得永磁电动机直接使轴（41）旋转，鼓（43）连接到远离永磁电动机（40）的轴（41），使得轴的旋转引起滚筒的相应旋转。永磁电动机（40）具有壳体（42），定位在壳体中的定子（62）和与定子配合的转子（64）。转子（64）具有固定在其上的驱动板（66）。轴（41）直接连接到驱动板（66）。轴承壳体（45）可旋转地支撑轴。
