Performax® 52 planetary gearhead
for a life in motion

The function of this drive technology:

Planetary gearhead Performax® 52.2 from ZEITLAUF® antriebstechnik makes sure patients can absolutely rely on the “Bi-Manu-Track” robotic arm trainer. Because this device makes a crucial contribution to the quick recovery of their motor functions by allowing them to have a positive, independent influence on their own therapy.

The most important features of Performax® 52.2 at a glance: 

• efficiency factor: n = 0.86
• reduction series: i = 21.25:1
• nominal output speed: 158 min^-1
• nominal output torque: 4.65 Nm
• nominal power output: 76.7 W
• max. permissible axial force: 500 N
• max. permissible radial force: 350 N
• drive shaft bearing: plain bearing / ball bearing
• lifetime: 5,000 hours
• protection rating: IP 40

The most important features of the DC motor with encoder at a glance:

• nominal voltage: 24 V
• nominal rotation speed: 3,350 min^-1
• nominal torque: 270 mNm
• nominal current consumption: 4.9 A
• nominal power output: 94.7 W
• idle-running speed: 3,650 min^-1
• protection rating: IP 50

The challenge:
The special challenge associated with developing the drive technology for the “Bi-Manu-Track” was the unknown torque to be reckoned with. Motion control is classically about controlling a motor designed for the particular load. Load reversal achieved by inputting active force can, however, be forgotten about in practice. However, with the “Bi-Manu-Track” robotic arm trainer it had to be kept in mind that the torque associated with a spastic hand can be several times greater than the output of the motor in normal operation.
