Technical Specifications:
The BLDC400 series motor operates at a rated voltage of 48V with a maximum no-load speed of 4000 rpm and a minimum no-load speed of 60/150 rpm. It has a no-load current of 0.5A and a rated speed of 3000 rpm. The motor delivers a mechanical power of 400W and a rated torque of 1.25 Nm, with a maximum momentary torque of 2.3 Nm and a holding torque of 3.7 Nm. The rated current is 10A, and the starting current is 1.5A. The motor achieves a maximum efficiency of 85% and can withstand a maximum housing temperature of 90°C, operating within an ambient temperature range of -20°C to +50°C.

Connections and Components:
The motor includes Hall sensors with specific phase connections: L1 Phase1 (U) white +5V DC, L2 Phase2 (V) brown GND, L3 Phase3 (W) grey H1, green/yellow GND yellow H2, and green H3. It features 3 electrical poles per phase, 6 magnetic pole pairs, and 3 phases. The terminal resistance is 0.49Ω, and the terminal inductance is 0.45mH. The torque constant is 0.12 Nm/A, and the speed constant is 62.5 rpm/V. The motor's starting time constant per 1000 rpm is 2600 ms, and it weighs approximately 2.3 kg.

Optional Features:
Optional features include sensorless operation, protection class up to IP67, customized connector plugs, connection cables of customized lengths, gearbox, brake, encoder, resolver, and tacho attachments, as well as electrical, mechanical, or geometric adjustments.

Operating Conditions:
The motor is designed for continuous operation (S1) at an ambient temperature of 22°C, reaching maximum permissible temperature under continuous load. It can also handle recurring momentary overloads (S3).

Designations for Enquiries:
The motor can be specified as BLDC400-xx with options for Hall sensors (HS) or sensorless (SL), e.g., BLDC400-HS.
