Synchronous AC motors run at a speed fixed by the input line frequency. Typically 60 Hz in the USA. Run a clock with the sync motor from the USA in England and it runs slow because they use 50Hz.
Asynchronous motors run at whatever free-run speed they feel like, and slow under load. A DC wound hand-drill is such a motor, runs pretty fast till you start drilling, then it slows down.
A synchronous motor will develop maximum power at its' designed speed, try to slow it down and it puts out more torque. Slow it down by overload, it doesn't create more power, it just creates more heat.
An Async motor creates highest torque at stall speed, least torque as it approaches maximum speed.

Difference between synchronous and asynchronous flip flops?
synchronous means it is based on a clock...it performs operations based on every clock tick....asynchronous operations execute irregardless of the clock signal
What is the difference synchronous buses and non synchronous buses?
Synchronous buses are clocked, and things happen only at the clock Ticks while in asynchronous buses a certain protocol must be used to enforce timing.
Can protocol is synchronous or asynchronous?
CAN Protocol uses asycnchronous communication. It is high speed 1 Mbps, short distance protocol.
What is difference between synchronous motor and synchronous condenser?
a synchronous condenser is over excited synchronous motor under no load
What is the definition of asynchronous?
Not in the same time.
Is VoIP a synchronous or asynchronous form of communication?
synchronous
What is the difference between synchronous IO and asynchronous IO?
If a process requests that the O/S write data to disk, and has to wait for it to be written before continuing, then that is Synchronous. If the process does not have to wait for the write to be completed, that is Asynchronous. Synchronous is real-time.
What is a slip in electricity?
it is the difference between the synchronous and asynchronous speed of a induction motor
Differecne between synchronous circuit and a asynchronous circuit?
Synchronous circuits operate under the influence of s clock pulse while asynchronous circuits operate without the influence of a clock pulse
Difference between synchronous and asynchronous flip flops?
synchronous means it is based on a clock...it performs operations based on every clock tick....asynchronous operations execute irregardless of the clock signal
Is rs232 synchronous or asynchronous?
It can be either.
What is the difference between synchronous and asynchronous interrupts?
i/o data transfer speed of time
Why the synchronous modems are more costly than the asynchronous modems?
Because they contain clock recovery circuits
What the different between synchronous and asynchronous?
In asynchronous transmission , the receiver and the transmitter each use their own clock signals so its not possible to know when a word starts and stops. while in synchronous , the receiver and the transmission have common clock signals.
What is is faster synchronous slc NAND flash or toggle MLc NAND flash?
Toggle is the fastest type of MLC NAND by a considerable margin. There is a larger performance gap between toggle and synchronous than there is between synchronous and asynchronous.
Difference between synchronous bus and asynchronous bus?
1. Syncrhonous bus includes clock in control lines whereas asynchronous bus is not clocked. 2. the devices which need to be connected by synchronous bus should be at same speed whereas an asynchronous bus may connect many devices with varying speeds. 3. A fixed protocol is defined to communicate using synchronous bus which is relative to the clock. An asynchronous bus uses handshaking protocol.
Difference between internal and external interrupt?
internal interrupt is synchronous with the program while external interrupts are asynchronous.
