How to Choose DC Motor&Motor Driver for Crawler Robot&Wheeled Robot
Crawler robots and wheeled robots are developing rapidly in intelligence today, and they are widely used in many fields. Crawled robots are generally driven by dual DC motors, while wheeled robots generally use a four-wheel drive design, with a single-axis or dual-axis DC motor driver to achieve the vehicle’s walking design. However, many customers are not so sure about how to choose a suitable DC servo motor or DC servo driver when selecting models. Today, I will share with you how the matching selection of DC servo motor and servo driver in the development of special robots is carried out.
Ⅰ. How to Choose Suitable DC Servo Motor & Reducer
When selecting a DC servo motor for a mobile robot, the total vehicle load (maximum load), driving speed, application scenarios, driving wheel design and motion requirements (straight, left and right steering, in-situ steering) should be considered. According to the requirements of total load and driving speed, the torque required for the mobile robot to travel straight can be simply calculated. While the application scenarios and motion requirements need to be considered separately, and combine the friction coefficient of the vehicle and the aspect ratio of the vehicle body to adjust the required output torque of the vehicle.
In our recommendation and selection process for customers, we will fully consider the high overload characteristics of Zhengzhou Defy self-produced DC servo motors, and make full use of the high overload characteristics of the servo motors to achieve strict control of product power and purchase costs for customers, which wins the recognition and praise of customers.
Ⅱ. How to Choose Suitable DC Servo Driver
Whether it is a crawler chassis or a wheeled chassis robot, after selecting a suitable DC motor, how to choose a DC servo driver or DC brushless motor driver that matches the motor is the key to determining whether the electric drive performance of the whole vehicle can be fully utilized. It is necessary to combine the action requirements and motor overload characteristics of various special robots under different application conditions to make a motor driver suitable for customers.
Based on professional knowledge and long-term good interaction with industry customers, the professional marketing team of Zhengzhou Defy has maintained double-percent product selection for many years, that is, the selection success rate is 100% and customer satisfaction is 100%.
At present, crawler robots are widely used and have diversified product forms, such as picking robots, spraying robots, lawnmower robots in modern agriculture, fire fighting robots used in the field of fire protection, spray robots used in modern epidemic prevention, mountain climbing robots, wall-climbing robots and other forms. Wheeled robots are mainly used in relatively flat terrain, such as electric inspection robots, warehouse inspection robots, etc.
