Among 1029 reliable rotation periods obtained from the surveys, we discovered 1 new large super-fast rotator, (40511) 1999 RE88, and 18 other candidates. (40511) 1999 RE88 is an S-type inner main-belt asteroid with a diameter of D=1.9+/-0.3km, a rotation period of P=1.96+/-0.01hr, and a light curve amplitude of {Delta}m~1.0mag. To maintain such fast rotation, an internal cohesive strength of ~780Pa is required. Combining all known large super-fast rotators, their cohesive strengths all fall in the range of 100-1000Pa of lunar regolith. However, the number of large super-fast rotators seems to be far less than the whole asteroid population. This might indicate a peculiar asteroid group for them. Although the detection efficiency for a long rotation period is greatly reduced due to our two-day observation time span, the spin-rate distributions of this work show consistent results with Chang+ (2015, J/ApJS/219/27), after considering the possible observational bias in our surveys. It shows a number decrease with an increase of spin rate for asteroids with a diameter of 3<=D<=15km, and a number drop at a spin rate of f=5rev/day for asteroids with D<=3km.2016ApJS..227...20Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/227/20CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/313 : Palomar Transient Factory (PTF) photometric catalog 1.0 (Ofek+, 2012)J/AJ/150/75 : Asteroid light curves from PTF survey (Waszczak+, 2015)J/ApJS/219/27 : Surveys of asteroid rotation periods using iPTF (Chang+, 2015)J/ApJ/743/156 : NEOWISE obs. of NEOs: preliminary results (Mainzer+, 2011)J/ApJ/742/40 : Jovian Trojans asteroids with WISE/NEOWISE (Grav+, 2011)J/ApJ/741/68 : Main Belt asteroids with WISE/NEOWISE.
