MAB17 - NEMA17 Brake

 
Electronic brake for all NEMA17 motors.
 
The electronic brake is designed to be mounted on step- and servo motors with NEMA17 flange 42x42mm. Brake itself have NEMA17 mounting dimension but flange size is 46x46mm. Brake can be mounted directly on stepper motor from JVL MST17x and also JVL integrated stepper motor MIS171, MIS173, MIS176 with 5, 6.35 and 8mm shaft. Brake can also be used on any other brand motor that use NEMA17 standard and have 5 , 6.35 and 8mm shaft. Output shaft can be 5 or 8mm. Shaft collars ring with 1 screw is used to tighten brake on motor shaft.
A high quality 24VDC electro-magnetic spring brake is mounted inside the housing. The brake use hub connection to brake disc so it can be mounted on motors with axial play. Holding torque is 0.5 to 0.7 Nm.
 
The brake is used when it is desired to hold the motor shaft fixed at power off, or when the motor is used in a vertical linear application. When 24 VDC is connected, the brake will be deactivated and the motor can turn freely. It is only recommended to use the brake only as a holding brake and not as an emergency brake.
 
All brake are equipped with M8 4 pin male connector for 24V control voltage.




 
  • Flange screws are not included, we recommend M3x60
  • In and output flange is equal Nema17 so a NEMA17 gear can be mounted on the front of the brake but notice the 4 mounting holes are turned 30 degree
  • With purpose can brake shaft move forward and backward 1-2mm to absorb potential temperature extensions
  • Pilot diameter is meant to be 27mm and not 22mm which is standard on a NEMA17. Due to tolerance in brake pilot or shaft measure can there be a risk that motor ball bearing can have limited lifetime if brake and motor have same pilot diameter. Remember to follow correct mounting procedure
