Function and application
As shipped from the factory, there are two designs of the MTR−... :
as servomotor
as stepping motor.
The first design, a permanently excited electrodynamic brushless servomotor,
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
values 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
electronics. 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 axes.
