NEMA (National Electrical Manufacturers Association) contactors and motor starters are rated by sizes. These sizes are grouped by rated current and power . [ 1 ] [ 2 ]
The MZ 202 was developed first as a 60 hp (45 kW) lightweight competitor to the liquid-cooled 64 hp (48 kW) Rotax 582.Later the MZ 201 was developed from the MZ 202 as a de-rated 45 hp (34 kW) version intended for motorgliders and single place ultralights that needed more power than the single-cylinder Zanzottera MZ 34.
It develops 300 bhp (224 kW; 304 PS), with an extra 60 bhp (45 kW; 61 PS) available from a driver operated 'push-to-pass' turbo boost button. Based entirely on road-car production engines and prepared and built by Mountune Racing , it only differs by utilising a Pi Research Pectel electronic fuel injection and a water-cooled Garrett T34 ...
The rating of a brushless motor is the ratio of the motor's unloaded rotational speed (measured in RPM) to the peak (not RMS) voltage on the wires connected to the coils (the back EMF). For example, an unloaded motor of K v {\displaystyle K_{\text{v}}} = 5,700 rpm/V supplied with 11.1 V will run at a nominal speed of 63,270 rpm (= 5,700 rpm/V ...
The EngineUS 45 motor produce 70 kW (94 hp) maximum and 45 kW (60 hp) continuously, has a power-to-weight ratio of 2.5 kW/kg at 2,500 rpm and an efficiency over 94%. [ 1 ] Applications
6D15 – 6920 cc, bore 113 mm × stroke 115 mm, peak power is 170–175 PS (125–129 kW), while the turbocharged 6D15(T2) has 230 PS (169 kW). The T3 has 245 PS (180 kW). 6D16 – 7545 cc, bore 118 mm × stroke 115 mm, ohv gear driven camshaft, direct injection with in-line injection pump, peak power is 170–185 PS (125–136 kW), n/a, turbo ...
Power ranged from 70 hp (52 kW) in US-spec versions via 76 PS (56 kW) in the non-catalyzed European models, to a turbocharged version with 120 PS (88 kW) (down to 110 hp SAE in the US). [23] Later versions received a twelve-valve head, as installed in the JT150 Gemini it offered 100 PS (74 kW) at 6,000 rpm.
For electrical motors, a similar kind of information is conveyed by the service factor, which is a multiplier that, when applied to the rated output power, gives the power level a motor can sustain for shorter periods of time. The service factor is typically in the 1.15-1.4 range, with the figure being lower for higher-power motors.
