1.Introduction：
HIWIN TMRW series torque motor is constituted of stator and rotor. A servo-drive
regulation ensures excellent acceleration capabilities and good uniformity of movement.
Due to the hollow shaft design, cable systems or mechanical parts can be fed through
without problems.
1.1 Unpacking instructions
Installation and operation of the motor must be in accordance with the HIWIN
manual. Before using the TMRW, please read these safety instructions and
precautions carefully.
caution
1. Before using the TMRW, please read these safety instructions
and precautions carefully. HIWIN is not responsible for any
damage, accident, or injury caused by incorrect handling.
2. Examine the appearance of the motor for any unusual marks
or damage from shipment.
3. Inspect the wires for any damage.
4. Do not disassemble the motor. Since the design of the
product has been based on structure calculations, computer
simulations, and prototype testing, do not disassemble the
product without the permission of HIWIN engineers.
5. Supervise children when handling this product.
6. People with psychosomatic illness or insufficient experience
should not handle this product, unless under the direct
supervision of managers or product narrators.
If any items are damaged or incorrect item, please contact your distributor or HIWIN
sales representative.

2.Basic structure of TMRW torque motor
HIWIN TMRW series torque motor is constituted solely of stator and rotor, exclusive of
bearing, positioning systems and other relative parts. The main structure is as Fig. 2.1
shows and below is the description:
Stator：With water cooing channels in the outer part, and it is made of aluminum alloys
or steel. The inner part is made of lamination stack and windings covered with
epoxy. Two cable outlets in one side, and that is motor power cable and
temperature sensor cable. Moreover, the stator should be placed on a stiff
foundation of customer’s machine.
Rotor：The main structure is steel ring with attached magnets and rotor should be
installed on the rotating part of customer’s machine. Due to rotor has high
magnetic forces of attraction, it needs to have well protection away from
magnetic objects (steel objects) when installing or shipping.

3.TMRW torque motor installation design
TMRW series (As Fig. 3.1) can be cooled by water or air. There is a water cooling
channels in the outer case of stator. And outside of the channels, there is an O-ring
equipped to be leak proof. As for the coolant inlet and outlet, these must be level with
the motor cable outlet to ensure good circulation of water cooling, to reach
cooling mechanisms. The recommended position of coolant inlet/outlet is shown
below:

3.4 Coolant inlet/outlet position when mounted horizontally
No matter whether the motor cable output is facing upward or downward, the outlet
should be at the top while the inlet is at the bottom. And that the coolant inlet and
outlet must be level with the motor cable outlet.

3.6 Rotor installation introduction
In order to prevent magnet interference and motor’s performance affected, there
should be some space (Fig. 3.5 Φd) between customer’s shaft and rotor magnet.
Table 4 defines the maximum dimension for the shaft external diameter inside the
stator and the flatness specification on rotor mounting level.
