Introduction 1 Introduction HIWIN torque motor, with the constitution of a stator and a rotor, can be directly driven without decelerator. With servo drive control, excellent acceleration and good uniformity of movement can be easily achieved. Due to the hollow shaft design, cable systems or mechanical parts can easily feed through the motor.
Assembly Instruction Introduction Warning notice system Safety notices are always indicated using a signal word and sometimes also a symbol for the specific risk. Different safety alert symbols refer to different types of dangers. Please be aware of personal safety while handling the goods with warning labels on it.
Ensure the product is used with rated load. According to IEC 60034-5 standard, all HIWIN torque motors have the following class of protection: IP20 for the stator and IP00 for the rotor. HIWIN torque motors have a insulation class F (TM-2/IM-2 series) and class B (TMRW series) according to ...

Proper use of the torque motors includes observing the assembly instructions and following the maintenance and repair specifications. Use of the torque motor components for any other purpose shall be considered improper use. Use only genuine spare parts from HIWIN. 1.3.2 Reasonably foreseeable misuse Torque motors must not be operated: Outdoors ...

Assembly Instruction Introduction 1.3.7 The danger of strong magnetic fields The permanent magnet in the torque motor rotor has a very strong magnetic field. When there is no input current, the strong magnetism of the motor comes from the permanent magnets on the rotor, and the magnetic field strength is inversely proportional to the distance (Fig.
Page 11
Do not directly touch motor parts after motor is assembled. If the current exceeds the maximum specified current, magnetic components in the motor may be demagnetized. When it happens, please contact HIWIN or local distributors. Do not operate the product in an environment that exceeds its rated load.

Motor sizing and T-N curve confirmation With the help of HIWIN’s motor specification, users can select the appropriate motor from peak torque and equivalent torque, and ensure speed and torque under all operating conditions is within the range of the motor’s T-N curve.
Page 23
Assembly Instruction Configuration < T Motor sizing is determined as follows. < T Users need to consider the ratio of equivalent torque and continuous torque. Generally, the ratio (T ) is recommended to be within 0,7. Continuous torque for TMRW/TM-2/IM-2 series can be classified into air cooling and water cooling.
Since rotational speed is directly proportional to frequency, iron loss will be larger at high speed. However, rotational speed for HIWIN torque motor is low, so iron loss is relatively less than copper loss. Rotational speed value indicated by HIWIN drawing and specification is the maximum peak speed that the motor can reach.
Page 25
Assembly Instruction Configuration 3.2.2 Continuous operating temperature Steady state temperature of motor coil is determined by the proportion of copper loss and iron loss. When rotational speed is low, iron loss may not be considered. Both total loss and rated continuous torque ( ) are defined when coil temperature is 120 ℃.
Assembly Instruction Configuration Thermal time constant The temperature of the coil of the motor is related to the thermal time constant during operation. The thermal time constant is defined as the time required for the temperature difference to reach 63.2% of the difference between the steady-state temperature and the initial temperature (Fig.
Assembly Instruction Configuration Power supply and controller selection The continuous current, peak current and bus voltage must be considered while selecting a power supply. In addition, the resonance effect which can be induced in motors by some drive systems must be taken into account.

Coolant selection Coolant needs to be prepared by the user. Anti-corrosion coolant needs to be used for HIWIN torque motor. The design and performance test of HIWIN torque motors are based on pure water. If customers use oil as the coolant, the heat that can be taken away by the same flow rate will be reduced and so will the motor power, otherwise the flow rate should be increased to keep the motor power.
