Rotolinear Green Drive
Rotolinear tubular motor sare composed by brushless rotative motor with rotary ball-spline connected to Green Drive tubular linear motor. With this mechanical configuration are possible independent rotary and linear motion. Space consumption is a flange dimension of 66×66 and 88×88 mm excluding the connectors on just one side. Mechanics guarantees high level of rigidity thanks to double row contact ball bearings. High static torque upto 45 Nm are achievable with rotational speed upto 4000 rpm thanks to high performance bearing. Rotation position feedback is created by resolver and linear position feedback is created by integrated Green Drive encoder. The motors are three-phase brushless standard controllable by standard servo drives. Two different rotary motor sizes are available as well as two tubular linear motor sizes to achieve rated force upto 51 N and rated torque upto 2.4 Nm. Maximum stroke of the motor is 200 mm.
