There are provided a motor device and a motor-driven type moving body that realize efficient cooling of a motor. The motor device includes a rotary shaft of a hollow structure, a motor section that rotates around the rotary shaft, a coolant circulation pipe that is connected to both ends of the rotary shaft and that constitutes a closed loop shaped coolant circulation path together with a hollow section of the rotary shaft, and a coolant flow control section that controls the flow of a coolant in the coolant circulation pipe. The motor device has a rotational speed sensor that detects the rotational speed of a motor and a temperature sensor that detects the temperature of the motor. The coolant flow control section receives detection information from the rotational speed sensor and the temperature sensor as inputs, and performs a control to accelerate the flow of the coolant in the coolant circulation pipe according to a rise in the rotational speed of the motor and a rise in the temperature of the motor.
