* This is a combination of motor, bracket, B10 drill chuck and PWM 20A speed controller, it can be used with saw blade to become a mini saw. * Engine Specifications: Rated Voltage: DC 12V, No-load Speed: 10000RPM, Charging Speed: 8800RPM Rated voltage: DC 24V, No-load speed: 20,000 rpm, charging speed: 17,600 rpm. Starting current: 4-5A Motor body diameter: 42 mm. Motor body length: 66.5 mm. Bar length: 16 mm. Bar diameter: 5 mm. * Stand Features: Length: 50 mm. Width: 52 mm. Height: 53 mm. Mounting Hole Diameter: 4mm Thickness of the bracket: 3 mm. * Speed Controller Features: Input Voltage: DC 10V-DC 60V (Ultra Wide Operating Voltage) Output voltage: Linear under load Control power: 0.01-1200W Rated current: 10A Maximum current: 20A (long-term use of 10A, 450W or less, pay attention to keep the module free from heat dissipation conditions. ); PWM duty cycle: 0% to 100% PWM Frequency: 25KHz Product Dimensions (L x W x H): 77 x 45 x 28 mm. Attention: 1. About PWM, please do not connect AC power directly (such as 110V AC), the input voltage of this controller must be DC 9V-60V, otherwise it will be burned. 2. Make sure the positive and negative connections are correct before turning on the motor speed controller, it will be damaged if the supply voltage is connected with wrong polarity. Package includes: 1 x DC Motor 1 x PWM Speed Controller 1 x Stand 1 x B10 chuck 2 x Screws 2 x Assorted Hardware Tools
