The demand and application of electric motor in industrial robot
The motor is used to drive the joints of the robot. The requirements are to have a maximum power-to-mass ratio and torque inertia ratio, high starting torque, low inertia, and a wide and smooth speed range. In particular, a robot end effector (hand gripper) should use a motor with as small a volume and quality as possible. Especially when a fast response is required, the servo motor must have high reliability and a large short-time overload capability. Specific use requirements:
Rapid.
The starting torque inertia ratio is large.
The continuity and linearity of the control characteristics, as the control signal changes, the rotational speed of the motor can continuously change, and sometimes the rotational speed is proportional to or proportional to the control signal.
Wide speed range.
Small size, small mass and short axial dimension.
Can withstand harsh operating conditions, can perform very frequent forward and reverse and acceleration and deceleration, and can withstand overload in a short time.
At present, AC servo motors with high starting torque, high torque and low inertia are widely used in industrial robots. Other motors, such as AC servo motors and stepper motors, are also applied to industrial robots depending on the application requirements.
