MTR−...
2 Method of operation and use
As from the factory the MTR exists in two designs:
as servomotor
as stepping motor.
In the first design, a permanently excited electrodynamic brushless servomotor, it
supplies resolver signals to the higher−order controller. These signals transfer the
angle of rotation of the motor related to a zero position. The controller functions in
a closed−loop control circuit and regulates the motor to the specified nominal va
lues for current, speed and position with a high degree of accuracy.
In the second design, a stepping motor is operated on a controller with power elec
tronics. The controller specifies the direction of rotation and the stepping angle in
the form of current pulses (steps). The motor must always be operated within its
characteristic curves, as overloading and excesssive acceleration values can cause
steps to be lost which are not then registered by the controller.
The MTR−... has been designed for driving electric linear axes.
