Austin C-Series engine in an Austin-Healey 3000 Mark II. The BMC C-Series is a straight-6 automobile engine produced from 1954 to 1971. Unlike the Austin-designed A-Series and B-Series engines, it came from the Morris Engines drawing office in Coventry and therefore differed significantly in its layout and design from the two other designs which were closely related.
Variable Speed Fire Pump Controllers were invented and released with a UL Listing for fire pump service in 2003 by Master Control Systems, Inc. [1] [2] Paragraph 10.5.5 in the 2003 edition of NFPA-20 recognized Variable Speed as an accepted method for operating the fire pump. Then in the NFPA-20 2007 edition, section 10.10 was added to clarify ...
The poles can be varied at a ratio of 1:2 and thus the speed can be varied at 2:1. [ 7 ] [ 8 ] [ 9 ] Normally, the electrical configuration of windings is varied from a delta connection (Δ) to a double star connection (YY) configuration in order to change the speed of the motor for constant torque applications, such as the hoists in cranes .
DeLorean Motor Company [1] (also doing business as Classic DMC) is a US company based in Humble, Texas, established in 1995 by Liverpool-born mechanic Stephen Wynne, [2] using the branding of the defunct automobile manufacturer.
Since positive displacement pumps and motors are used, one revolution of the pump or motor corresponds to a set volume of fluid flow that is determined by the displacement regardless of speed or torque. Speed is regulated by regulating the fluid flow with a valve or by changing the displacement of the pump or motor.
From 1951 until 1977, White Motors also distributed Freightliner Trucks. [34] This took place under an agreement with Freightliner's parent, Consolidated Freightways. White manufactured trucks under its own brands—White, Autocar, and Western Star—as well, leading to the company becoming known as the "Big Four" through to the mid-1970s.
Through Kissel Manufacturing Company, they distributed engines for various manufacturers and developed their own gasoline engines including outboard boat motors. The partnership was also involved in home building and sales through, a stone quarry, sand pit, and facilities for milling their own finished lumber. [3]
For high quality rotating drive systems, plunger motors are generally used. Whereas the speed of hydraulic pumps range from 1200 to 1800 rpm, the machinery to be driven by the motor often requires a much lower speed. This means that when an axial plunger motor (swept volume maximum 2 litres) is used, a gearbox is usually needed.
