It depends entirely on the motor design. The only universal disadvantage of a DC motor (vs. an AC motor) is the need for a DC power supply (DC power is more difficult to transmit efficiently over long distances, hence the use of AC for typical power grids).
Typical brushed DC motors (the cheapest and hence one of the most common type of DC motor) tend to wear out eventually due to friction and draw MUCH higher current when stalled than when turning, which can cause overheating. They are also typically heavier than AC motors with similar specs. Of course all of these problems can be eliminated by using a (slightly more complex) brush-less motor design.

What is a DC shunt motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
What are uses of bidirectional dc motor?
6V dc motor
Can DC series motor work on ac and DC and why?
A dc series motor can work on dc and ac because dc motors are totally reversible.
How does a DC brushless motor work?
To state it simply, a DC brushless motor is not a DC motor. It is an AC motor with an inverter (or electronic commutator) on the front end to make the AC, so you can use a DC input.
What are brushes with reference to DC motors?
Bushes, with reference to DC motors is a brushed DC motor which is a motor that designed to run from a direct current (DC) power source. This type of motor is an internally committed electric motor.
what are a few of the disadvantages to a brush-less motor controller?
The brush-less motor controller has a smaller output current than one DC motor. The brushless also has less of a output voltage. The maximum output voltage is 50V, where a regular DC motor would have a maximum of atleast 60V.

What is dc motor with synchoronous operation?
A synchronous motor is an ac motor that does not run on dc.
Can DC series motor work on ac and DC and why?
