1. Gear Ratio
Gears are generally used to reverse the direction of rotation, increase and decrease the speed of rotation. It is important to keep the rotation of the axis synchronized. Most gears have teeth, of which prevent slippage between the gears ensuring synchronization at all times. By counting the numbers of the teeth in the two gears and dividing them finds out the exact gear ratio.
2. Climbing Ability
Depending on the torque of the motor and the gear ratio of the transmission this will be able to verify how far the vehicle can climb. With a 18.12.1 differential gear ratio it allows our EMC vehicles climb with a great deal of effectiveness.
3. The AC v DC Electric Motor
A.C and D.C Motors are similar in function but powered differently. An A.C Motor is powered by an alternate current, whereas the D.C Motor is powered by a direct current. At EMC we typically supply a D.C Motor which are battery reliant with brush components. Both motors have their strengths with the A.C Motor being more energy efficient with power usage. Whereas a D.C Motor has a higher starting torque. However due to growing popularity of A.C. Motors with the higher efficiency within the A.C Motor, it is now becoming the norm in the electric vehicle industry to opt for an A.C Motor. All of our new MY20Vantage Range come with A.C Motors.
