Publication number: 20210363704Abstract: A method of controlling a DC motor that includes the step of providing a pulse-width modulation (PWM) signal to the DC motor. The PWM signal provides a voltage to operate the DC motor. The method also includes the steps of measuring a voltage generated by the DC motor when the PWM signal is off. In more particular embodiments, the method includes measuring a current being supplied to the DC motor when the PWM signal is off. The method may further require determining a motor speed of the DC motor based on the measured voltage. The method further includes controlling the DC motor to maintain a relatively constant motor speed with varying loads on the DC motor.Type: ApplicationFiled: August 3, 2021Publication date: November 25, 2021Applicant: Sno-Way Intemational, Inc.Inventors: Robert N.

Patent number: 10745875Abstract: In one embodiment, a hopper spreader apparatus for spreading granular material is provided. The hopper spreader apparatus includes a hopper, a spreading unit, and a dispensing unit. The hopper has a storage cavity for storing the granular material to be spread. The spreading unit spreads the granular material. The dispensing system transports the granular material from the hopper to the spreading unit. The dispensing system includes a conveying unit and a rotating first roll. The conveying unit conveys the granular material toward the spreading unit. The rotating first roll controls a flow of granular material from the hopper to the conveying unit. The use of the rotating roll allows for control of high flow material (such as for example dry salt) while allowing for improved collapse and break-up of low flow material (such as for example wetted sand).Type: GrantFiled: October 15, 2015Date of Patent: August 18, 2020Assignee: Sno-Way International, Inc.Inventors: Robert N.
