To operate your motor, you simply hook up 2 wires to the battery, correct? That is a big clue that it is a brush type DC motor. A brushless motor (BLDC) with 2 wires would need an electronic controller inside the motor housing. That is seldom done in the size and type of motor you have, a hydraulic pump drive unit for automotive/truck/industrial applications.
The nameplate indicates that motor is rated for intermittent duty of 5 minutes or 15% on-time which is unlikely to stabilize thermally at any continuous load.
