So to take your example of a 10kg weight, to lift this at a speed of 1 m/s would require a power: $$ W = 10 times 9.81 times 1 = 98.1W $$ which is well within the power of your 750W motor. Alternatively you could flip this around and ask how fast you could lift
2016/12/7A BLDC motor overcomes the requirement for a mechanical commutator by reversing the motor set-up; the windings become the stator and the permanent magnets become part of the rotor. The stator is typically comprised of steel laminations, slotted axially to accommodate an even number of windings along its inner periphery.

2021/2/23Horsepower, sometimes abbreviated to PS (German for "Pferdestrke"), therefore refers to the power output generated by a horse in order to lift a 75 kg weight one meter high in one second. Under the metric system, it is equal to around 736 W. So the motor output of an electric vehicle can be stated interchangeably in either kW or PS.
Electric motors are used in a wide range of applications, from large industrial equipment such as in mining operations, down to small appliances like hair dryers. The majority of electric motors draw less than 0.75 kW of power and are used in the

Requirements Of Transmission System :- Provide means of connection and disconnection of engine with rest of power train without shock and smoothly. Provide a varied leverage between the engine and the drive wheels Provide means to transfer power in opposite direction.
2015/5/22I have a small dc motor, which is rated for 12V, 3A (rated ). When the motor runs with a load 4000N, the current consumption is 1.5A. So I have to choose a 12V, 3A = 12 * 3= 36W power supply to run the motor.This is because DC power supply can supply continous 3A current without any disturbance. Now I wanted to run same motor on battery.
2 Figure 2 Motor Power Factor (as a Function of % Full-Load Amperage) Overloaded motors can overheat and lose efficiency. Many motors are designed with a service factor thatallows occasional overloading. Service factor is a multiplier that indicates how much a
Minimum efficiency standards for electric motors will soon increase
2014/9/26The updated electric motor standards apply the standards currently in place to a wider scope of electric motors, generating significant estimated energy savings. DOE's analyses estimate lifetime savings for electric motors purchased over the 30-year period that begins in the year of compliance with new and amended standards (2016-45) to be 7.0 quadrillion British thermal units (Btu).

Determine the power requirement and the rpm of the motor of a double strand, chain no. 80 that is used for a rock crusher at a speed of 300 rpm. The number of teeth of the small sprocket is 21 teeth and the speed ratio of the drive must be less than 6. What
Electric motor catalogs usually state the efficiency and power factor at full load and at various part loads(for example at no load, 25%, 50%, and 75%). Curves can be fitted to these points (as shown), but our problem is that we don't know the absorbed power and in fact that is precisely what we want to calculate: an iterative solution is required; ie.
Using power MOSFETs in DC motor control applications
2021/9/28There are a few motors in sunroof and power tailgate applications. The motors can control the sunroof forward/backward and up/down, therefore the driving stage is required to allow bidirectionality. Both brushed and brushless DC motors can be used in this application, the former driven by a H-bridge ( Fig. 12 ) and the latter using a multiphase half-bridge ( Fig. 13 ).

2021/11/30Motor control centers are simply physical groupings of combination starters in one assembly. A combination starter is a single enclosure containing the motor starter, fuses or circuit breaker, and a device for disconnecting power. Other devices associated with the motor, such as pushbuttons and indicator lights may also be included.
Calculation of Shaft Power in Marine Engines on Ships
2015/11/7n (rpm) = engine speed. The effective engine power, Pe. Pe = k2 n pe (kW or bhp) where, n (rpm) = engine speed. Due to the friction in the thrust bearing, the shaft power is approx. 1% less than the effective engine power. From this calculation of shaft power in marine engines can be carried out on ships.
