Short description of device, technical data
The PMD 230-BL04 / 08 / 12 -4.0 is a 4-quadrant-transistor-controller to drive
brushless dc-motors up to 1,6kW.
Specifications of brushless de-motor:
No maintenance required, because there are no carbon brushes
Only wear are the ball bearings
The speed-torque-relationship is that of a dc-motor:
The nominal torque is available at all speeds. There is no slip! The control of the
torque (e.g. coil drives) may simply be done by controlling the motor current. The
motor current and the torque are proportional to each other.
Optimum power is achieved from minimum motor size.
Apposed to previous dc-motors there is no heat in the rotor. The heat is produced
in the stator and is easily emitted. The rotor has no current. Irrespective of the
motor speed (maximum torque with low or/at zero rpm), no ventilator is required.
Motor speed or motor torque is fully adjustable. The actual speed is measured with a
2 track encoder built into the motor. The encoders impulses can be used to control
the positioning. If required a reference impulse is available. An “impulse preparation
board” may be ordered optionally. This board supplies the encoder signals A, B, 0
normal and: inverted in 5V (TTL) or 15V switchable. Further option “Impulse
separator” is used to divide down the encoder impulses.
The speed nominal value is set with an external voltage -10V...+10V or with a
potentiometer (5kOhm). This can be lead with an optional Integrator (Type SI-012).
Acceleration and deceleration ramps may be set separately (cw/ccw).
If necessary, the maximum torque can be steplessly adjusted from zero to
maximum by means of an external voltage. 0...+10V DC or an external
potentiometer (5kOhm).
The double nominal motor current can be programmed for accelerating and
decelerating. When standing the maximum torque is available.
The optional “ positioning control ” replaces a mechanical brake in many cases:
The motor shaft is blocked to maximum torque by means of an external contact
or the Input voltage.
Optional: Malfunction relay.
The controller switches off and a potential free contact is opened when malfunction
(e.g., overheating, short circuit, excessive braking or missing braking resistance)
occurs.
The motor can be switched off free of current (control release) by means of opening
an external contact (or NPN-switching transistor).
