Synchronous motors are those that run only at Synchronous speed ie.. constant speed.
JK flip flop are synchronous ONLY when the rise or the fall edge of the clock will transfer the data to the outputs

ADVANTAGES OF IDS
Synchronous
It is used in variety of applications such as... · Machine Tools such as a ball mill · Motor generator sets · Synchronous clocks · Timing devices · Synchronous condensers to condition electrical power · Record players · Robotics
A synchronous counter is not referred to as a ripple counter. They are two different things. The ripple counter uses the output of each stage to trigger the input of the next stage, resulting in propagation delay between stages. The synchronous counter, on the other hand clocks all stages on the same clock edge, making them all change at relatively the same time.
Basically it is a Synchronous Counter. You can google for further information.
Binary Counter
1. Easier to design 2. No propagation delay Actually the second one is the most important reason. In designing circuits that work at high clock rates, ripples will result in errors so synchronization is very very important.

A ripple counter is a counter in which state transitions of one or more flip flops are triggered by the outputs of other flip flops in the circuit. If all flip flops in the counter are triggered by a common clock pulse, then the counter is called a "synchronous counter". a ripple counter is a counter that will ripple through the information sequentialy. .
clock signal divider
a digital countdown timer is simply a digital synchronous counter consisting of registers and flip flops example :to count the number from 0 to 15 we require a four bit synchronous counter which will pass to sixteen stages continuously with shifting from one stage to other after every clock pulse and the cycle continues
mainly alternator,synchronous motor comes under the synchronous machine.a synchronous motor is not a self starting motor.if a synchronous motor moves with more than synchronous speed then it acts as a synchronous generator.
