DC Motor Controllers

DC motors can be simply connected to a power supply according to their rated voltage in order to make them run, but if you want to have control over direction, velocity, and acceleration in real-time, you'll need to use a motor controller. In order to connect this motor to a controller, you can connect the wires to the motor terminal on the controller. Don't worry about wiring the motor backwards; doing so will only reverse the direction of rotation. This motor requires higher voltage than our small motors, so only the following controllers are suitable:

Product		Electrical Properties		Controller Properties			Board Properties
Part Number	Price	Supply Voltage Max	Continuous Motor Current Max	Number of Motor Ports	Velocity Resolution	Acceleration Resolution	Controlled By
1065_1B PhidgetMotorControl 1-Motor	$75.00	28 V DC	5 A	1	0.39 % Duty Cycle	24.5 % Duty Cycle/s	USB (Mini-USB)

DCC1003_0 2x DC Motor Phidget	$60.00	30 V DC	(per motor) 4 A	2	0.001 Duty Cycle	0.1 Duty Cycle/s	VINT

Encoders

The rear shaft of this motor can be equipped with an encoder for applications where you need to keep track of the exact position, velocity, or acceleration of the motor. The mounting holes on the back of this motor are compatible with the following encoders:

Product		Encoder Properties
Part Number	Price	Output Circuit Type	Encoder Resolution	Encoder Speed Max
3531_0 Optical Rotary Encoder HKT22	$25.00	Push-Pull (Single-Ended)	300 CPR	6000 RPM
ENC4109_0 40 CPR Quadrature Encoder	$10.00	Push-Pull	40 CPR	6000 RPM

Shaft Couplers

If you need to connect the main shaft of this motor to another device with a shaft, you can use a shaft coupler:

Product		Physical Properties
Part Number	Price	Inner Diameter	Material	Coupling Rated Torque	Coupling Rated Speed	Torsional Stiffness
TRM4317_0 Jaw Coupling Half 12mm Series 12	$3.60	12 mm	Aluminum	35.7 kg·cm	12000 RPM	—
TRM4318_0 Jaw Coupling Half 12mm Series 24	$6.85	12 mm	Aluminum	611.8 kg·cm	4000 RPM	—

Pulleys and Sprockets

If you're using this motor to drive a rotary system that requires a lot of torque, you may be interested in pulleys and sprockets. By using a two pulleys or sprockets of different sizes, you can increase the gear ratio of the motor. Pulleys and sprockets can also be used to transmit the motor's rotation over a long distance. For more guidance on building a transmission system, visit our Rotary Motion Primer. Here is a list of our 12mm bore pulleys and sprockets:

Mounting Brackets

Mounting this motor to a flat surface is easy with these metal mounting brackets. The holes on the bracket match those on the front of the gearbox. The following brackets will fit the mounting holes on this motor:

Product		Physical Properties
Part Number	Price	Mounting Plate Size	Material
3339_0 Stepper Mounting Bracket (NEMA 23)	$4.00	NEMA - 23	Mild Steel (Coated)

Rotary Bearings

Systems with heavy loads or pulley/sprocket assemblies often put a lot of sideways strain on the motor shaft. If you're using this motor to drive such a system, you can use rotary bearings to protect the motor:

Product		Physical Properties		Mechanical Properties
Part Number	Price	Inner Diameter	Bearing Type	Static Load	Dynamic Load
TRM4502_0 Flanged Rotary Bearing for 12mm Shaft	$4.00	12 mm	Rotary Shaft (Flanged)	2.4 kN	5.1 kN
TRM4503_0 Pillow Block Rotary Bearing for 12mm Shaft	$4.00	12 mm	Rotary Shaft (Pillow Block)	2.4 kN	5.1 kN
