Rotary type (RF)
Three types that are newly added to the TRANSERVO series, slider table type, rotary type, and belt type, are introduced. Universality, energy-saving and low impact achieved with multi-position positioning unique to motorized devices. Compact rotary axis type. High-precision bearing specifications are also available.
01 New control method combines the best features of servo and stepping motors!
Stepping motors provide great features such as low cost , yet they have a drastic drop in torque at high speeds and heavy current consumption when stopped.
The TRANSERVO by YAMAHA eliminates all these problems by adopting an innovative vector control method. In effect, the TRANSERVO delivers the same functions of a servo motor while using a lower cost stepping motor.
Control is basically the same as a servomotor so power consumption is kept to a minimum, which saves energy and helps cut down on CO2 emissions.
Also perfect stop can be achieved as the same as with ordinary stepping motors so choose this setting if needed.
02 Environmentally rugged resolver provides closed loop control
The resolver used for detecting the motor position is the same reliable resolver as used in our high-level robots. Resolver offer stable position detection even in harsh environments containing dust or oil, etc. Addtionally the resolution of the resolver is 20480 pulses per revolution.
