Page 15: External Motor Wiring
Fuse values should be selected according to the RMS current rating of the motor. For most applications slow-blow type fuses should be used. When the motor is part of an Aerotech system utilizing an Aerotech controller and drive, the “A ” continuous current rating of the motor must be used to set the motor over-current protection fault. -
Page 16: Hall-Effect Device And Thermistor Wiring
BM/BMS Brushless Motor Hardware Manual BM/BMS Brushless Motors 1.4.4. Hall-Effect Device and Thermistor Wiring The insulation of these wires should have a rating for at least the maximum voltage applied to the motor wind- ing. The temperature rating of the wire insulation must also be sufficiently high to withstand the operating temperatures specific to the application. -
Page 17: Thermal Protective Device
BM/BMS Brushless Motors BM/BMS Brushless Motor Hardware Manual 1.4.6. Thermal Protective Device BMS motors incorporate a positive-temperature coefficient (PTC) thermistor as a thermal protection device. The nominal resistance of the thermistor is 100 ohms at 25°C. The thermistor exhibits a rapid increase in resistance to 1,000 ohms as the motor temperature approaches the thermistor’s transition temperature of... -
Page 18: Figure 1-3: Typical Thermistor Interface Circuit
BM/BMS Brushless Motor Hardware Manual BM/BMS Brushless Motors This thermistor can be used in a variety of different electronic interfaces. A precaution when using this type of device in an interface circuit is to avoid self-heating effects. An excessive amount of current through the thermistor will cause its temperature to rise. -
Page 19: Hall-Effect Operation And Motor Phasing
BM/BMS Brushless Motors BM/BMS Brushless Motor Hardware Manual 1.5. Hall-Effect Operation and Motor Phasing Aerotech brushless motors are shipped from the factory with the correct motor phase to Hall effect rela- tionship. Figure 1-4 shows the proper Hall effect to motor phasing for both clockwise (CW) and counter- clockwise (CCW) motor rotation viewed as shown. -
Page 20: Figure 1-5: Test Setup Configuration
Note the peak of the sine wave of channel 3 in comparison to the peak of the sine wave of channel 1. Aerotech phasing expects ØC to be the lead signal in time, ØB to follow it, and ØA to follow ØB. This means that whichever signal has been determined to lead the others in time is designated as the ØC winding. -

Page 24: Motor Heating
BM/BMS Brushless Motor Hardware Manual BM/BMS Brushless Motors 1.7. Motor Heating The temperature rise above ambient establishes a limit on the amount of current allowed through the motor winding. The thermal characteristics of the motor, the effectiveness of the surrounding medium to transfer heat away from the motor, and any supplemental cooling determine the operating conditions. -
Page 25: Maintenance
BM/BMS Brushless Motors BM/BMS Brushless Motor Hardware Manual 1.8. Maintenance Installation problems usually reveal themselves early in the installation. Regular preventative maintenance should include but is not limited to the following: make frequent checks for excessive or abnormal motor heat- ing, excessive motor vibrations, loose motor to machine couplers, obstructed air flow to the motor, burning smells, an accumulation of debris on the motor, etc. -
Page 26: Environmental Specifications
The motors are not to be used in wash-down environments (unless ordering with the IP65 option). Dust Exposure: The BM and BMS motors are rated IP40. The BM250, 500, 800, 1400, and 2000 can be ordered, as an option, with IP65 protection. Altitude: Up to 2000 m. -
