The rated speed is 3000 rpm and the rated torque is 2.4 Nm, compatible with industrial voltages ranging from 400V to 480V. The motor adopts an optimized magnetic circuit winding and a lightweight rotor structure, achieving efficient power output within a very small body size. It has high power density and fast dynamic response, meeting the requirements for miniaturization and integration of equipment design. It can operate continuously and stably for 24 hours in complex working conditions in the workshop.

Model Specifications  

Product Application

The B&R 8MSA2S.E1-B6 brake servo motor is mainly designed for medium and small loads, high-frequency dynamics, precise positioning, and vertical fall prevention scenarios. It is specifically used as a dedicated supporting motor for vertical automation equipment, cantilever modules, and lifting mechanisms.

Electronic intelligent manufacturing equipment: 

vertical dispensing machines, loading and unloading transplanters, precise detection lifting mechanisms, micro bonding equipment, ensuring precise locking of vertical positions and eliminating deviation.

Light mechanical hands and servo modules: 

three-axis and four-axis vertical sliding tables, lifting servo modules, cantilever handling mechanical hands, loading and unloading robotic arms, with self-locking to prevent falling in case of power failure, ensuring safe and stable operation.

Packaging and printing equipment: 

vertical packaging machine lifting mechanisms, laminating and cutting lifting modules, label machine precise feeding mechanisms, suitable for high-speed continuous positioning and locking requirements.

Current inventory and efficient supply chain guarantee

The Maohui warehouse is equipped with heavy-duty multi-layer industrial shelves. Inside, clear coding labels and information-based location management are adopted, including B&R (B&R), Siemens (Siemens), Schneider (Schneider), Lenze (Lenze), and Bosch Rexroth (Bosch Rexroth), etc. Whether it is commonly used servo motors (such as B&R 8MSA, 8MS series), drive modules or relatively rare discontinued spare parts, there is a rich inventory to ensure that each incoming spare part is traceable, significantly improving the efficiency of picking and inspection when leaving the warehouse.

Product Classification and Quality Inspection Standards

The B&R 8MSA2S.E1-B6 of China Maohui Machinery is different from ordinary servo motors without brakes. This product is equipped with the original factory electromagnetic brake and is specifically designed for vertical loads, cantilever installation, and scenarios requiring power-off positioning and locking for precise automation. It is the core supporting model for vertical mechanisms in the electronic manufacturing and non-standard automation industries. Inspection process: power-on function test, encoder accuracy verification, rated load test, long-term aging operation, fault parameter reset. Through comprehensive screening, hidden defects and returned faulty equipment are completely eliminated. The delivered performance is close to the new standard. After installation, the equipment can be directly put into production use.

Q1: Which working conditions can the brake-equipped version be applied to?

A: It is specifically designed for vertical lifting, cantilever suspension, Z-axis positioning, power-off retention, and anti-fall scenarios, such as vertical modules, lifting manipulators, and detection alignment mechanisms. It is not suitable for scenarios where there is no need for braking and the load is purely horizontal and light.

Q2: Which types of drives are compatible? Is it necessary to connect a separate brake power supply?

A: It is originally compatible with all models of B&R ACOPOS drives. The brake supports drive linkage control, and can be matched with a dedicated brake control circuit. The wiring is simple, the linkage is precise, and the start/stop and locking are synchronized without conflicts.

Q3: How about the service life and stability of the brake?

A: The original factory industrial-grade brake assembly has undergone high-frequency braking durability tests. The locking torque is stable, without slipping or attenuation. It is suitable for industrial long-term high-frequency start-stop operations, and has extremely strong stability.
