AB  - Rotary	nanomotor,	as	the	essential	component	of	a	dynamic	nanomachine,	can	output	rotation	via	its	rotor.	
So	far,	several	techniques	e.g., electric-,	nanofluid-,	laser-,	chemical-,	and	thermally-driven models, have	been	
proposed to	actuate	a	rotary	nanomotor,. Among	 the	 techniques,	 the	 thermally-driven	rotary	nanomotor	
(TDRM)	models	are	the	simplest	technique	that	does	not	require	an	accurate	external	field	as	into	energy.	
The	model	says	that the	thermal vibration	of	the	atoms	in	the	nanomotor	can	transmitted	into	rotationally	
kinetic	energy	via	a	rotor.	Cai	et	al.	[1]	discovered	the TDRM	when	relaxing	double-walled	carbon	nanotubes	
(CNTs)	 at	 an	 NVT	 ensemble.	 Soon	 after,	 such	 thermal	 ratchet	 nanomotor	 with	 controllable	 rotational	
direction	was	built	by	the	team	[2].	Based	on	the	principle,	the	rotary	nanoring	models	[3],	measuring	the	
giga-hertz	rotation	of	the	nanomotor	[4],	diamond	needles-driven	CNT	[5]	or	graphene	flake	[6]	to	rotate	
were	realized.	Li	and	Han	[7]	introduced	a	defective	graphene	to	drive	the CNT-rotor.	Recently,	Cai	et	al.	[8]	
studied	the	dynamic	response	of	a	bladed-rotor	sinking	in	water	when	driven	by	both	thermal	vibration	and	
an	 external	 rotary	 electric	 field.	 Further	 research	 is	 required	 for	 developing	 new	 TDRM	 models	 with	
controllable	output.
