The Three-One Motor BL and BLh series are the core lineup for general laboratory and industrial stirring applications. Understanding the differences between general-purpose and high-power (high-torque) models helps you select the right motor for your specific requirements.
General-Purpose Models (BL Series)
The BL Series covers standard laboratory stirring from low to medium viscosity. Key characteristics:
- Rotation speed: 5–3,000 rpm (model-dependent)
- Maximum torque: up to 1.3 N·m
- Suitable for: aqueous solutions, solvents, light suspensions
- Power: 100 V AC, 50/60 Hz (overseas power supply available as an option)
- 5-year limited warranty with user registration
High-Power Models (BLh Series)
The BLh Series provides higher torque for medium to high viscosity applications. Key characteristics:
- Rotation speed: 5–3,000 rpm (model-dependent)
- Maximum torque: up to 2.6 N·m (twice the BL Series)
- Suitable for: viscous fluids, pastes, suspensions, larger volumes
- Power: 100 V AC, 50/60 Hz (overseas power supply available as an option)
- 5-year limited warranty with user registration
