More Information
Summary:A drive system and a motor actuator are provided. The drive system includes a motor actuator and a drive arm. The motor actuator includes a housing, a motor mechanism, a harmonic gear mechanism, a connecting mechanism, an oil seal, and a braking mechanism. The motor mechanism and the harmonic gear mechanism are respectively disposed in a first chamber of the housing, and the harmonic gear mechanism is connected to a shaft of the motor mechanism. The connecting mechanism is connected to the harmonic gear mechanism. The oil seal is disposed between the harmonic gear mechanism and the shaft. The braking mechanism is arranged in a second chamber of the housing. The brake mechanism can selectively reduce a rotation speed of the shaft. The drive arm is connected to the connecting mechanism. Accordingly, the oil seal can prevent leakage of lubricating grease in the harmonic gear mechanism, so that the drive system can greatly increase the service life.
