robot joints of the driven motor is needed, and brushless motor has fully meet the requirements of robot joint features. Robot joints, therefore, need to use brushless motor, and demands for brushless motor has these features: 1, starting torque, moment of inertia than the big, in the case of driving load, the requirement of the robot's driving motor starting torque, moment of inertia of small, fast response, 2 brushless motor from get instructions signal to complete the required working state of time should be short. Response signals of the shorter time, the motor system, the higher the sensitivity, rapid response performance better, the general is the size of the electrical and mechanical time constant brushless motor to illustrate the performance of brushless motor response quickly. 3, wide speed range, can be used in 'speed range of 0 ~ 10000. 4, the control characteristics of the continuity and linearity, as the change of control signal, brushless motor speed can change continuously, sometimes still need speed is proportional to the control signal is proportional or approximation. 5, small size, the quality is small, the fuselage length, trunnion sizes is short, this is the one big characteristic of brushless motor, suitable for space robot installation location small feature requirements. 6, can be very frequent direction and deceleration operation, and can withstand overload in short time, can run under tough conditions. According to the statistics, high starting torque and high torque and low inertia of communication has the brush motor, brushless dc motor, stepper motor, dc servo motor has widely used in industrial robots. Average load of 1000 n (A 100 KGF)The following industrial robots are mostly adopt dc motor drive system. Adopted by the robot joint joint driving motor are mainly BLDC brushless DC motors, stepper motor and the DC servo motor. Stepping motor driven system more suitable for precision, speed, demand is not high, small simple open loop system of the robot, brushless dc motor with the reversing, non commutation spark and has been widely used in the inflammable and explosive environment. Robot joints drive motor power range of 0. 01 ~ 10 kw。 Industrial robot drive system used in brushless motor as introduced to above available, servo, stepper, brush motor, brushless motor itself has small volume, low quality, fast response, large starting torque inertia ratio etc features, combined with the robot joints also have these qualities, so the brushless motor was better cater to the trends of the development of robot industry applications.
