Product catalog summary
Technical Specifications:
The UF1.S motor operates at a rated voltage of 24 V DC with a tolerance of +/-10%. It achieves a maximum no-load speed of 3300 rpm and a minimum of 200 rpm. The motor's no-load current is 0.5 A, with a rated speed of 3000 rpm. It delivers a mechanical power of 150 W continuously and a rated torque of 0.5 Nm, with a momentary maximum torque of 0.8 Nm. The rated current is 6.8 A, and the starting current is 1.4 A. The motor's maximum efficiency is 85%, and it can withstand a housing temperature of up to 90°C, operating within an ambient temperature range of -20 to +50°C.

Connections:
Power connections include L1 (24 V DC – 28 V DC), L2 (GND), and PE. Hall sensors are connected via white (+5 V DC), brown (GND), grey (H1), yellow (H2), and green (H3).

Characteristics:
The motor features 9 electrical poles/phases and 12 magnetic pole pairs, with 3 phases. It has a winding insulation class of F, terminal resistance of 0.41 Ω, and terminal inductance of 0.35 mH. The torque constant is 0.07 Nm/A, and the speed constant is 137.5 rpm/V. The starting time constant per 1000 rpm is 0.5 seconds. The motor weighs approximately 1.3 kg and uses Chainflex cables for power and data connections. It has a protection class of IP50.

Operating Conditions:
The motor is designed for continuous operation (S1) and can handle momentary overloads (S3 20%) for up to 1 minute. The default configuration includes stripped and tinned power and data connections, with optional customizations available such as sensorless operation, higher protection class up to IP67, customized connector plugs, and gearbox attachments.

Additional Information:
The datasheet includes a schematic diagram for the operating range and instructions for setting switching times for Hall sensors. The document notes that all specifications are subject to change without notice and emphasizes the need for specific quotations for particular use cases.
