Abstract
A motor apparatus having an oil circulation structure may collect churning oil inside a housing and efficiently disperses the collected oil in each drive system, smoothly performing cooling and lubrication of the drive system including a motor and a reduction gear. Furthermore, even under low or high load conditions of the drive system, the oil level inside the housing is maintained at a constant level to maintain desired lubrication and cooling performance.
