The equation to calculate the motor torque required is shown below for a gear system with 35:1 ratio and 80% efficiency. M mot = M L i* η G . M mot = 865 mNm 35*0.80 =30.89 mNm=0.03089 Nm . Depending on the efficiency of the gearbox, the torque required from the motor can vary by a significant amount. In Figure 16 below, motor torque is ...

KT = motor torque constant (N-m/A). Ke = motor EMF constant (V-sec/rad) TL = load torque (N-m) Tf = frictional torque. If the motor is unloaded then TL is zero and the value of Tf limits the motor speed to the no-load value.

W1L1=W2L2. This product of force times the distance between the force and the axis around which rotation occurs as the result of the force is called torque. Torque is defined as the product of the length of the radius and the force perpendicular to the radius.

The sum of the individual drive motor torques (see Motor Specifications ) must be greater than or equal to the computed required Wheel Torque. The Maximum Tractive Torque represents the maximum amount of torque that can be applied before slipping occurs for each drive wheel.

An increase in torque accelerates the motor until the balance between applied voltage VB and IR+Km is re-established. The angular velocity is not restored to its original value because when current increases, the IR term on the right side of the equation increases, so the motor accelerates to an angular velocity less than it was before.
