|---|---|
| Airflow at 0 Pa | 285 m³/h |
| Speed | 13,000 rpm |
| Power | 50 W |
| Voltage | 48 V DC VAC |
| Motor frame | The casing is square with dimensions 92 × 92 × 38 mm and made of plastic. Mounting screws of type ISO 4762 M4 (degreased, without washer) are used for fastening. The mounting position is optional with respect to the orientation of the motor shaft. The maximum tightening torque in the mounting holes is 30 Ncm. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and rotates clockwise when viewed from the rotor side. The airflow is directed outwards over the struts. At free airflow and 13,000 rpm, a maximum airflow of 285 m³/h and a maximum static pressure of 800 Pa are achieved. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with electronic speed control via a PWM signal (1–5 kHz). The nominal voltage is 48 V DC with an allowable voltage range of 20–58 V. The motor has reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The locked rotor current is approximately 3800 mA at nominal voltage. |
