DESCRIPTION

The MDrive NEMA 34 high torque Integrated Motor and Driver is ideal for designers who want the simplicity of a motor with on-board electronics, but without the expense of an in- dexer on each axis. The low cost MDrive34 puts the system designer in the driver’s seat to decide the best method of control. The MDrive34’s integrated electronics eliminate the need to run the motor cabling through the machine, reducing the potential for problems due to elec- trical noise.

The MDrive34 uses a NEMA 34 frame size 1.8° high torque mo- tor combined with a microstep- ping driver, and accepts up to 14 resolution settings from ½ to 256 microsteps per full step. Setup pa- rameters include Microstep Resolu- tion, Motor Run/Hold Current, and Motor Direction with respect to the direction input. These settings may be changed on-the-fly or downloaded and stored in nonvolatile memory with the use of a simple GUI which is provided. This eliminates the need for external switches or resistors. Parameters are changed via an SPI port. MDrive34 operating voltage ranges from +24 to +75 VDC.

The MDrive34 is available in multiple configurations to fit various system needs including a single shaft rotary motor with optional internal optical encoder, a dual shaft rotary motor with control knob, a planetary gear- box, or a long life Acme screw linear actuator. The rotary MDrive34 is available in single, double and triple stack sizes: 24, 31 & 47. Interface

connections are accomplished using 12.0" (30.5cm) flying leads.

The MDrive34 is a compact, pow- erful and inexpensive solution that will reduce system cost, design and assembly time for a large range of stepping motor applications.
