Brand new original Mabuchi 755WC motor, high power, high speed, high torque, the appearance of the two motors are the same size, but the applicable voltage is different, they are all Violent 755 motors used in power tools, the power is above 200W, locked rotor The current is above 125A, and the locked-rotor torque is above 8.8KG/cm. They are all classic electric tools 755 motors.

775WC-8514 Rated voltage DC 14.4 V

775WC-8017 Rated voltage DC 18 V

The external dimensions of the two motors are the same:

Motor diameter: 42 MM (plus the guard ring is 46.3 MM)

Motor length: 67 MM

Motor shaft diameter: 5 MM

Output shaft length: 12 MM (measured from the panel)

Motor weight: 326 grams

A model (755WC-8514) measured parameters are as follows: (rated voltage 14.4V)

Voltage: DC14.4V

Current: 2.4 A (locked-rotor current: 125 A)

Speed: 18500 rpm

Torque: 1.13 KG/cm (stall torque: 8.8 KG)

The measured parameters of model B (755WC-8017) are as follows: (rated voltage 18V)

Voltage: DC18V

Current: 1.8 A (locked-rotor current 120 A)

Speed: 19200 rpm

Torque: 1.13 KG/cm (locked-rotor torque 8.8 KG)

A violent DC motor must be supported by a powerful power supply. If the current of the power supply is not large enough, the power of the motor cannot be used. Don't look at its no-load current only about 2 A, but check it from the website of Wanbaozhi Motor According to their data, their locked-rotor current exceeds 125 A. Generally, the electric tool motor is powered by a high-power lithium battery. If it is powered by a switching power supply, the current of the power supply must not be less than 30A, the larger the Well, if it is small, the speed, power and torque of the motor cannot be used, or even start.

The power of these two motors is very powerful, high-speed and high-torque. They were originally designed for power tools, circular saws, and gardening tools, but they are also suitable for DIY model power, miniature spindle motors... etc. They require small size. , But where the power is large and the torque is large.

But it needs to be reminded: like this kind of high-power density motor, it is not suitable for long-term work, please pay attention to the heat dissipation work environment.
