CHANCS Motor 775 DC Saw Circular Saw Mini Electric Motor DC 12V/24V Speed 10000RPM/20000RPM With 20A PWM DC Motor Speed Controller

*This is a DIY combination of a mini saw. Contains motor, bracket, B10 drill chuck, saw blade, and 20A DC Motor Speed Controller. *The specification of motor: Rated Voltage: DC 12V, Unloaded Speed: 10000RPM, Load Speed: 8800RPM. Rated Voltage: DC 24V, Unloaded Speed: 20000RPM, Load Speed: 17600RPM. Starting current: 4-5A, Motor Body Diameter: 42mm, Motor Body Length: 66.5mm, Shaft Length: 16mm, Shaft Diameter: 5mm. *The specification of PWM: Input Voltage: DC 10V-DC 60V (Ultra wide working voltage)； Output voltage: linear under load； Control Power: 0.01-1200W； Rated Current: 10A； Max Current: 20A (Long-term use of 10A, 450W or less, pay attention to keep the module free of heat dissipation conditions.)； PWM Duty Cycle: 0%-100%； PWM Frequency: 25Khz； Product Size(L x W x H): 77*45*28mm； This is a DC 10V-60V 20A DC Motor PWM Speed Controller,Its own power supply reverse polarity protection, control voltage over-voltage protection, 20A fast-blow ceramic fuse. *The specification of bracket: Length: 50mm, Width: 52mm, Height: 53mm, Mounting hole diameter: 4mm, Thickness of bracket: 3mm. *Attention: 1re use to ensure that there is no gap between the saw blade and the spindle, tighten the nut. 2se do not connect AC power directly(Such as:110V AC),the input volt of this controller should be DC 9V-60V,otherwise it will be burned out. 3 speed regulator is for use with DC brushed motors. It is NOT suitable for speed regulation of DC brushless motors; nor can it be used as a voltage regulator or voltage stabilizer! 4tive and negative pole of the POWER and the MOTOR can NOT be reversed.
