The MFH170i has a diameter of 170mm and is available in three stack lengths of approximately 114, 130 and 155mm with peak torque ratings of 8.5, 11.9 and 16.9Nm. Rated speeds are between 750 and 1000rpm whilst the 360 line encoder has a programmable resolution of up to 59 million counts per rev. The motor requires a 48Vdc supply voltage and also features an efficient motor constant rating to suit mobile applications.
The brushless torque motor-drive's 20kHz PWM servo control features Allied Motion's sinusoidal SVM commutation for smooth operation and fine positioning. A choice of position, velocity and current loops, with update rates of 500, 200 and 100µs respectively, combine with primary and secondary command inputs that can be configured for analogue voltage or current control.
Further possibilities for position control are available with CANopen or Modbus RTU fieldbus and .NET framework. The controller also includes 6/3 programmable inputs/outputs and a single analogue output. Protection features include bus under- and over-voltage, short circuit, I2T as well as drive and motor over-current.
