8JSB stainless steel servo motors
8JSB and 8JSQ - Servo motors for hygienic applications
The B&R servo motors in the 8JSB and 8JSQ series feature a hygienic design that allows efficient cleaning in the areas of foodstuffs production and biomedical engineering. With their smooth surfaces and IP69K protection, they were developed strictly in accordance with EHEDG and FDA hygiene standards.
8JSB and 8JSQ stainless steel servo motors
The B&R servo motors in the 8JSB and 8JSQ series feature a hygienic design that allows efficient cleaning in the areas of foodstuffs production and biomedical engineering. With a smooth surface and IP69K protection, these motors were developed in strict accordance with EHEDG hygiene standards. This makes them the optimal choice for harsh environmental conditions or areas where machines are working with aseptic processes. These motors are characterized by the highest power density in this class. The smooth stainless steel housing with a surface finish of less than 0.8 µm, rounded corners and seamless transitions have been designed to eliminate undercuts and protruding screws in order to prevent the collection of contaminants while allowing for simple, safe and efficient cleaning. With a laser-engraved type plate and IP69K protection, these motors are extremely suitable for efficient daily cleaning processes.
Advantages of B&R stainless steel motors for your application:
- Simplified installation and maintenance through plug-in connectors
- Robust B&R single cable solution with built-in hybrid connector for safe drives
- Complete hygienic design in accordance with EHEDG and FDA guidelines for optimal washdown
- 100% stainless steel (housing, flange, shaft and connectors)
- Innovative connectors with IP69K protection and hygienic design
- Food-safe and resistant to chemicals
- Ideal for machines with an open design
- B5 and B14 mounting methods
The use of B&R's single cable (hybrid) solution with digital feedback reduces the number of feed-throughs to an absolute minimum. The connectors also have IP69K protection and meet hygiene standards. The hybrid cables with FDA approval are heat resistant up to 150°C and provide automatic pressure compensation. These features result in even higher operational safety while eliminating outages caused by the formation of corrosion or condensation inside the motor. The robust B&R single cable solution with built-in hybrid connector allows these motors to be seamlessly integrated in the B&R system environment, and their safety functionality opens up entirely new possibilities for automation in the foodstuffs and pharmaceutical industries.
Embedded parameter chip
All relevant mechanical and electrical information and data is stored in the EnDat encoder used for B&R three-phase synchronous motors. This means that the user doesn't have to configure settings on the servo drive. As soon as the encoder is connected to the servo drive and power is applied to the electronics, the motor is automatically identified. The motor sends its nominal parameters and limit parameters to the servo drive. The drive then automatically determines the current limits and current control parameters required for optimal control of the motor. The only things that the user has to optimize are the speed and position controllers. The integrated commissioning environment in B&R Automation StudioTM provides all necessary support.
In addition to assistance during commissioning, routine service work is also simplified, and motors can be exchanged without having to take extra time to set parameters.
The hygiene motors in the 8JSB and 8JSQ series are self-cooled and have a stainless steel design. They are only available as a single cable (built-in hybrid connector) solution with a "straight" connection direction. The mounting method is the only difference between them.
The 8JSB series is designed with flange-mounted construction.
The 8JSQ series is designed with front-mounted construction.
8JSB / 8JSQ three-phase synchronous motors are available in size 3, 4, 5 and 6.
They have different dimensions (especially flange dimensions) and power ratings. These different sizes are indicated by a number represented by (c) in the model number. The larger the number, the larger the flange dimensions and power rating for the respective motor.
