Thingap Slotless Brushless Pm Motor With Optional Integral Encoder

The ThinGap® brand TG1500 Series Slotless Brushless PM Motor with optional integral encoder of Ventura, CA, incorporates new stator winding technology that eliminates eddy current and hysterisis losses and achieves 89% peak system power efficiency. The TG1500 brushless dc motor operates over a wide speed range (0 to 4000 rpm). The TG1500 size 23 brushless servo motor series is compatible with NEMA 23 mounting requirements. A maximum continuous torque of 120 ounce-inches is achieved at 2450 rpm rated speed point using an operating voltage of 24 vdc and 15.6 amps to the TG1500 series motor from the specified PWM servo amplifier. The optional integral optical encoder provides 4096 lines per revolution with an 20 times interpolation feature that yields 81,920 counts per revolution. Other encoder mounting options available.

The thin wall of the stator coil allows a miniature air gap to be utilized in combination with the high energy Neodymium-Iron-Boron magnets to create a high power density brushless PM motor. With no magnetic hysterisis, low speed cogging is non-existent. Armature inductance measures 10 microhenries and line-to-line resistance is 0.3 ohms @ 25°C.

The TG1500 series is thermally rated for high performance operation up to 160°C temperature rise plus ambient conditions. Motor unit size measures 2.375" OD by 2.240" long. The optional integral encoder has a larger 2.85" by 2.25" rectangular footprint by 0.52" axial length. Total motor-encoder package length is 2.76".
