Why does the load torque of the hub motor used in robots be very high?

The robot's hub motor is a commonly used drive motor with the advantages of lightweight, high efficiency, and easy control. However, when using a hub motor to drive the robot, the load torque is very high. Mainly because the wheel hub motor is an efficient electric robot driving device with the advantages of simple structure, easy installation, high reliability, high power density, and high efficiency. Compared with traditional driving devices, hub motors do not require transmission shafts and reduction gearboxes, which reduces friction losses in the transmission mechanism, reduces the energy consumption of the robot, and improves the efficiency of the entire system.

First, you need to understand the load torque conditions that the robot may face during work. When the robot moves, due to the influence of friction, inertia, gravity and other factors, a certain load torque will be generated. Especially when performing acceleration, deceleration, turning and other actions, the load torque will be more obvious.

As a drive motor, the wheel hub motor needs to withstand and overcome these load torques. The size of the load torque is related to factors such as the robot's mass, shape, motion state, etc. If the robot's structural rigidity is not enough, the load torque endured by the hub motor will be greater.

Therefore, it is normal for the hub motor to bear a high load torque when the robot is in motion. But that doesn't mean hub motors aren't suitable for robot drives. On the contrary, by rationally designing the robot structure, selecting a suitable hub motor, and strengthening the control of load torque, efficient movement and stable operation of the robot can be achieved.

In addition, the hub motor can achieve non-contact driving, that is, driving through the interaction of magnetic fields, thereby avoiding friction and wear caused by the transmission shaft, greatly reducing the maintenance cost of the robot. In-wheel motors have high power density and torque density, can achieve high output power and torque in a small space, and can meet the needs of high-load applications such as robots moving at high speeds and climbing slopes. At the same time, the high efficiency of the hub motor can also reduce the energy consumption of the robot in high-load applications and improve the robot's working time and efficiency.
