The BRA018-064038-LX is a DC linear brush motor from H2W Technologies designed for applications requiring precise linear motion. It features a continuous force output of 38 N at 125°C and a peak force of 114 N at a 10% duty cycle. The motor operates with a continuous current of 5.0 amps and can handle a peak current of 15 amps under similar conditions. The motor's resistance is 1.4 ohms at 20°C and 2.2 ohms at 125°C, with an inductance of 2.4 mHenrys and a time constant of 1.7 milliseconds at 20°C. The motor has a travel distance of 457 mm and a back EMF of 8.0 V/m/sec. It is important to note that the motor does not include built-in linear bearings, requiring the user to provide a suitable bearing system to maintain the necessary air gap of 0.03 inches (0.7 mm) between the magnet and coil assembly.
Linear brush motors are not supplied with built-in linear bearings. The guidance of the magnet assembly along the top of the laminated coil assembly must be provided for by the customer supplied linear bearing system. There is a magnetic attractive force between the magnet and coil assembly. The short magnet assembly is normally the moving component. Higher forces can be achieved by increasing the number of poles (longer magnet assembly) or by increasing the width of the motor. The customer supplied bearing system must maintain an air gap of 0.03" [0.7 mm] between the magnet and coil assembly.
