Depending on what you're referring to, you may have this completely backwards. A motor's efficiency is fairly high. A generator's efficiency at converting chemical/kinetic/mechanical energy to electric energy is at best around 50%.

Can a motor act like an electric generator?
when the motor runs more than rated speed it produces leading current and results act as a generator. (or) the motor act as generator when it produces more back e.m.f
who is more efficient dc motor or ac motor and why?
DC motors are generally more efficient than AC motors. DC motors have a lower amount of inertial associated with them, making them more efficient to run.
Is a Diesel Generator more efficient than a gas one?
No, it's actually less efficent.
Can an electric motor run a generator to power itself if the motor has a small gear and the generator has a big gear?
I think it can work with a certain type of generator and an electric motor like one that uses 300w/h The idea is to run a generator that can produce more electricity than needed to run the motor that is powering it.
What is the difference between energy efficient motor and normal motor?
in EEM copper material used is more than the normal motor.the EEM has more efficiency around 95% than the normal motor.
Will using a transformer to convert 230V to 12V DC consume more energy than using a few capacitors and resistors without a transformer?
no, the transformer is much more efficient <><><> HOWEVER- a transformer only changes the voltage of AC current- it does not change it to DC. You will still need diodes or rectifiers. You can also use a motor/generator- a 230v AC motor turns a 12 v DC generator.
Why the efficiency of generator is more than the motor in case of swinburne's test?
the generator windings are made of more thicker windings . Hence lesser resistance and lower Cu losses
How much electric motor do i need to run a 1500watt generator?
Hi, Figure 25-30% more than generator capacity. If you are trying to get more out than you put in, then the Laws of Physics preclude this. Peace, crigby
Is it possible that you use motor as a generator input and electricity of the generator provide to a motor as a input?
If I'm understanding the question, you are proposing using one motor and one generator, and have the motor spin the generator up to speed, and have the generator attempt to supply power to the motor. The answer is yes, you can do this, but you will be losing energy, not gaining it. The motor and generator's efficiencies are less than 100%, so once you remove the outside source they will slow down until they come to a complete stope, without any other load connected other than themselves.
What are the differences between the parts of a generator and the parts of a motor?
In principle a generator is the same as a motor. In a dc motor the voltage generated by the rotating armature is slightly less than the supply voltage which causes power to flow in from the supply. If an engine is then coupled to the shaft causing it to rotate faster, then it generates more voltage and power flows back into the supply. That is how a motor becomes a generator.
How is an electric motor different than an electromagnet generator?
Some types of motor can work equally well as a generator. A DC motor runs on a DC supply and supplies a mechanical load. If the load is removed the motor will free-run a little faster. But if the shaft is then driven faster than that, the current flows the opposite way and the motor has become a generator.
What generator is suitable for a 2 HP single phase motor?
Any single-phase a.c. generator producing more than 2.5 HP or 2 kW - at the required voltage.
