Abstract

The invention discloses a flexible exoskeleton integrated motor control driver and a motor. The motor control driver comprises a motor control circuit, a high-speed photoelectric coupler, a logic gate circuit, a motor drive circuit and a motor power amplification circuit which are connected in sequence; the motor control circuit is connected with a potentiometer used for collecting the rotation of the motor through an AD sampling circuit; the power supply end of the motor power amplification circuit is connected with the power supply through a filtering rectification circuit; and the signal end of the motor power amplification circuit is connected with a controlled motor. The potentiometer signal of rotation of the controlled motor is collected through the AD sampling circuit; the collected signal is filtered, amplified, sampled, maintained, quantized and coded through the motor control circuit, so that AD conversion can be completed, and a stable PWM pulse and a forward and reverse rotation signal F / R are output; after an output control signal passes through the high-speed photoelectric couple and the logic gate circuit; a corresponding field effect transistor is controlled to be conducted through the motor drive circuit and the motor power amplification circuit, so that the power-on control of the controlled motor is realized; and therefore, the purpose of driving the motor to operate is achieved.

technical field [0001] The invention relates to a motor, in particular to a flexible exoskeleton integrated motor control driver and a motor. Background technique [0002] As high-efficiency motors become a development trend, high-efficiency and low-consumption motor control schemes have naturally become the general trend. Through effective motor control, the goals of fast start-up, fast response, high efficiency, high torque output and high overload capacity of the motor can be achieved. Traditional motor drives have problems such as high cost, low efficiency, and time-consuming, which are manifested in: [0003] First, a triode with sufficient current must be provided for switching processing. The motor runs at a relatively low speed, and the motor vibrates and generates heat. [0004] Second, the requirements for circuit design are relatively high, the requirements for circuit anti-interference are relatively high, it is easy to cause high frequency, burn out the driving...

AI Technical Summary

Problems solved by technology

[0003] First, it is necessary to provide a triode with a large enough current for switching processing. The motor running speed is relatively low, the motor vibration is relatively large, and the heat is large.

[0004] Second, the requirements for circuit design are relatively high, the requirements for circuit anti-interference are relatively high, it is easy to cause high frequency, burn out the driving components, and the requirements for component performance are relatively high

[0005] Third, the circuit is relatively complex, and it is difficult to control the interference in the circuit to meet the theoretical requirements, and it is easy to generate jitter. When controlling the peaks and troughs of the sine wave, it is easy to cause high-frequency interference, which in turn causes the drive components to heat up or the frequency is too high. Ageing
