1 Features

The baseboard BB-160 allows to build a ready to use BLDC motor driver unit using the TMCM-160 driver module. All important signals and the power supply lines can be connected easily. For motor, power supply and hall sensors screw terminals are available and for RS232 (or RS485) a 9-pin D-SUB connector. Some signals like the analog inputs are adjustable either onboard or they can be controlled remotely.

Applications

• fast prototyping of motion control applications with BLDC motors (e.g. lab use)

• ad-hoc evaluation of the TMCM-160 module without the need of developing a custom PCB

• BB-160 + TMCM-160 suitable for series production

Highlights

• screw connectors for motors and hall sensors for fast prototyping

• access to all control inputs of the TMCM-160

• screw holes for reliable mounting beyond prototyping

• compact size (120 mm x 85 mm)

• setting of motor velocity and current (torque) with the help of two potentiometers

3 Electrical and Mechanical Interfacing

3.1 Pinning

Caution:

1. Do not connect or disconnect the TMCM-160 module, the baseboard or the motor while the system is powered on. This could damage the drivers of the TMCM-160 module.

2. The TMCM-160 has two complementary connectors on each side. Make sure the module is inserted correctly (pay attention to the orientation of the logo in the figure below). Wrong insertion of the module will most probably damage the TMCM-160. The motor and power connector of the TMCM-160 has to be next to those on the BB-160 (the top of the Trinamic triangle points towards the motor connectors).

3. Before powering up the unit make sure the TMCM-160 is inserted correctly (correct direction of board, no misalignment of pins, board firmly inserted).

4 Operational Ratings

The operational ratings show the intended / the characteristic range for the values and should be used as design values. In no case shall the maximum values be exceeded.

Symbol Parameter Min Typ Max Unit

VS Power supply voltage for operation 15 36 40 V

Environment temperature -25 +60 °C

ENV

Table 4.1 : Operational Ratings (pls. refer [TMCM-160])

The power supply has to be disconnected when plugging in a TMCM-160 module into the BB-160. Do not connect or disconnect the motor while the unit is powered. Connecting or disconnecting the motor while the unit is powered might damage it.

4.1 Power supply requirements

The power supply should be designed in a way, that it supplies the nominal motor voltage at the desired maximum motor current. In no case shall the supply voltage exceed the upper voltage limits. To be able to cope with voltage which might be fed back by the motor, the supply should provide a sufficient output capacitor and / or a 39V suppressor (zener-)diode.

4.2 Motors

The TMCM-160 operates with a wide range of block commutated 3 phase BLDC motors with hall sensors. Motors with 12, 24 or 36V (ask for 48V option) nominal voltage or any value in between are supported with a coil current up to 3A nominal , 5A with forced cooling (up to 8.5 A current for short time).
