Introduction

The ZGB37REE382i 12VDC motor has:

• Manufacturer - Wenzhou Zhengke Electromotor Company Ltd
• Description - Zheng Gear Box Motor 1110A003
• Speed - maximum of 5 RPM
• Voltage - 12VDC
• Current - 0.58A
• Shaft diameter - 6mm
• Shaft length - 15mm
• Mounting - face mount, five M3 screws

Speed Control

The motor speed is reduced to a maximum of 5 RPM through its built-in gears.

By subjecting the motor to a PWM controller, speeds down to ⅓ RPM is possible.

Our controller is a PIC16 with PWM output. The PIC16 PWM unit is capable of 10 bit resolution at a variety of frequencies; however, an 8 bit PWM resolution already produces an imperceptible change in speed.
